Isomorphous Interactions Between Zirconium and BOV/20-125-4-56/T4
Titanium
The structure analysis confirmed on the whole the formula of
this mineral (according to M. Tb. Kazakova and Yes, 1. Semenov,,
Ref* Na aZr3Ti3~n2 [,,iO4]eF4. The most essential change car-
out by the authors was the affiliation of a third of Ti
to Zr and the removal of each 8th O-atom from the silicon-oxy-
gen radical (which is less visible for the analyst). The two
interpretations by Ye. 1. Semenov (Ref 2) are from the first
dangerous in view of the numbers obtained by a detailed analy-

the case of.Seydoserite in its~cation distribution as was con-
firmed by the X-ray structure analysis of the authors. Only
two maxima were determined on the corresponding projection.
One of them may be ascribed to the Mn-eation, the other one to
the Ti. After the identification of the higher maximum with Mn
the-authors.immediately discovered a mistake in the case of
the distances between these two cations and the surrounding 0-
-atoms. This mistake could be correcied only by the exchange
of Ti and Mn. It could, howeverl not be concluded from the

contraryv the chemical and radiographic analysis pointed out
clearly that a fourth of Zr is replaced by Ti. Thus the assumai
isomorphism wouldbe in any case unilateial. After the detec-
tion that 1/4 of the Zr-atoms is replaced by Ti in Seydosprite,
and correspondingly the halt of the Xg-atoms by Mn, not 1_.1y ,
one, but 2 paradoxes are solved. The Mn which inclines towards
high oxidation degrees is transformed from the bivalent state
into a trivalent (or ? even tetravalent) one. Correspondingly
the tetravalent Ti becomes trivalent (like in the case of~py-
roxene, Ref 4). The reaction T14+ + Mn2+i=!T13+ + Mn3+ (Xn4+,?)

ABSTRACT: The investigation of the ouspidine'structure (Ref 1) became
an important step towards further investigations of several
Ca-silicates, above all of wollastonite and xonotlite (Ref

The variety of the motives to which this group belongs in the
Ca-silicates is considerably limited by a certain inertia of
.the diorthotic groups and the existence o: onl on di ction

.with a dimension of 3-7f I (height of the grou Pi 1:1
cursive). Thus a "tilleite band" occurs in both initially
mehtioned.Ca-silioates as a mineralogical radical (Figs 1. 1).
Figure I shows that a part of the ti'lleite band.consists of
8 octahedra and two IS'207] groups. The 14 O-atoms of the two.
last groups are, however, not sufficient to counterbalance
the cation charges. This is compensated (according to Ref 5)
by additional anions F, OH in the ouspidine structure. The
latter oonsistp completely of tilleite bands of a most simple
formula3 Ca 8[~i 20 712(F' OR)4- 2Ca. 415'2071 (F, OH) 2 *
The second variant of the two most simple geometrical
solutions for such a formula is realized in nature. In this
case the members of Ca-octahedra of a tilleite band continue
Card 2/4 one another in forming somewhat longer 4-membered members.

It seems that the latter strengthen the structure since they
lie one behind the other. In the strunture of tillsite itself
the tilleite bands are not fused, they are related to one
another by additional CO 3-groups. This demands the
introduction of an additional Ca-octahedron as well, so that
the formula will be Ca 41si 2~71CO3 -caco3(Fig 2).,In,1958
(Ref'6) new data on the hidrothermal synthesis of the
substance mentioned in the title (TSH) were published and a
formula suggested. If the formula of the tillqite band is
reduced from the formula of TSH 2 portlandite molecules Ca(OH)2
are obtained. It is assumed that these were replaced in the
formula to the "side chain" outside the cuspidine nucleus
(Table 1). They form a third layer with their 4'.OH particles
which links the'tilleite bards (with 2 layers).'The additional
Ca-octahedra (Fig 3) which replace,the CO 3 groups in tilleite
Card 3/4 are placed here as well. The authors draw the conclusion that

TITLEt On Wdhlerite-Lovenite and Rinkite Mosandrite Groups

PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 126, Nk 2,
pp 379-381 (USSR)
ABSTRACT: The 2 groups named in the title followed each other in
modern text-books (Rafe 1, 2) and in mincralogical tables
(Ref 3). Despite a somewhat closely-connected type-formula,
they differ greatly with respect to their shape and the
parameters of the elementary cells. The recently published
results of an exhaustive investigation of the Zr,Ti-silicate
of Lovozero - the Seydhozerite (Refs 4, 5) change'~he
mineralogical picture considerably. This mineral was placed
by its discoverer (Ref 6) into the Wdhlerite-lovenite group
(zrO 2-content - 23 %). According to r6ntgenometrioal data
it doubtlessly belongs to the Rinkite group. Moreover, this
mineral should because of its ideal structure be'placed on
Card 1/3 top of the Seydhozerite-Rinkite-group. The same test of the

On Wdhlerite-Lovenite and Rinkite Mosandrite Groups BOV/20-126-2-42/64
structure (Figs 4, 5) proved.that ouspidine should be placed
on top of the Wbhlerite-Lovenite-group. In the essential work
on the cuspidine and other purely mineralogical publications
much space was devoted to its close structural connection with
another Ca-silicate, the tillite. By means of geometrical
analysis of this simplest Ca-silioate there was determined
an infinite mineralogical radical - the tillite band which
all minerals have in common (Fig 1). With the aid of this
band such an important compound as tricalciuzailicate-hydrate
(Ref 8) is for cement-chemistry, could simply be npUt
together" and a structural solution could be found. A second
interesting result obtained in consequence of +ae tillite
band determination is the aforementioned geometrical
(structural) difference between both mineral groups$ mentioned
in the title. Hence further (rational) combination of both
these groups, which are already connected by a common type-
formula is necessary. From figures 2-4, one may see that the
minerals of the Cuspidine-Mlerite-Lovenite group are (at
least from the geometrical standpoint) only a polymorphous
modification of the mineral group Seydhozerite-Rinkite.
Card 2/3 Perhaps in this case the term polytypical modification would

be more convenient. This modification is characteristically
expreased by the projection-surface of the cell which is
nearly the same if slight differences in the length of the
axis are not taken into account, In real minerals (MU 1)
above all the composition changes. There are 4 figures,
I table, and 8 ref erenoev., 7 of vhich are Soviet and

ABSTRACT: B. A. Tavger (Ref 1) showed a short time ago that the point-
symmetry (macrosymmetry) of ferromagnetios is described by the
31st group of the total number'of 90 Xheyeah-Shubnikov groups
(plus-minus groups, black-and-white groupo), The main
veotor is known to be the most characteristic element of
ferroelectrics as well as of ferromagnetics, but in ferro-
magnetics it is a polar iectoT, and in the case of ferro-
electrics it is ari ordinary axial vector. The maximum symmetry
of the axial vector i's oo 21 21 p and that of the polar

TITLE; Trl~P-ro-mewr-ur-urystai Chemistry of Silicates
PERIODICAL: Kristallografiya, 1960, Vol 5, Nr 1, PP 15-18 (USSR)
ABSTRACT: The 7-year plan of the X-ray Laboratory at the
CrystallograPhical Institute (Ren".-genostrukturnaya
Laboratoriya Instituta Kristallografii) includes the
further development of' crystal chemistry of siLicates
as an urgent problem because of its importance for the
industries producing refractory alloys, ceramics,
glass, cement, etc. Crystal chemistry, particularly,
that of silicates, was initiated in the USSR in 1935
with the organization of the X-ray Laboratory at the
Crystallographical Institute In Moscow,: but after a
brief period of studies and experiments, Interest to the
subject cooled-off. Then, in 1953 when new ideas on
the structure of silicates became urgently needed to
Card 1/3 explain some structures inconsistent with the Bragg

'The Problems of Crystal Chemistry of Silicates 78093
SOV/70-5-1 -2/30
theory, to produce and develop new silicates and
refractory alloys for industry, the Crystallographical
Institute became very active, and new research centers
such as those in Gorlkiy and Baku were organized. A
new idea emerged that, contrary to the Bragg theory,
the structure of silicates is not determined by the
combination of SIO 4 tetrahedra, but by the combinatien
of octahedrally coordinated cations, while chemically
inert silicic radicals just adopt the spaces left
between, and tetrahedra or their combinations deform
themselves to fit into the spaces,between well arranged
cations. If the latter are small N., Fe, AI)j.octa-
hedra edges are of about the same length as the edges Of'
Sio tetrahedra. Larger cations (Zr, Ti, Nb, Ta, Mn)
on ~he other hand, form octahedra who'se edges are too
long for SiO and, consequently, fills in the
4 31207
remaining spaces forming double rings, do,,.ible chains,
etc. Thus, atomic radii of cations determine two
Card 2/3 principally different types of structures, of which

The Problems of Crystal Chemistry of Silicates 78093
SOV/70-5-1-2/30
those formed by small cations are subject to Bragg's
theory, while the others, with Si.07 combinations,
give rise to a new chapter in the crystal chemistry
of silicates. There are also combinations of the two
principal types. Since refractory and other properties
of silicates are direct functions of their structure,
new concepts on crystal structure are important and
will be developed still further.

ABSTRAdT: The Cayley squares for point groups 432 and m3 of
qubic System are compiled in a four-page table to
assist theoreticians in crystallography; also
simplified-designations for symmetry operations used
in the table are explained'. A reference is made to
a letter by E.-Tavora (13razil) stating that he was
the first who emphasized great significance of
Cayley squares In crystallography. The figures
for point roup-43m. can easily be obtained from the
table for ~32 by substituting 7 and m for 4 and 2,
respectively. Similarly, point groups m3 and 23
differ only because of the occurrence of two-:fold

TITLE,-. The Crystal Structure of Baddeleyite (Monoclinicl-zlro
1 2)
PERIODICAL: Kristallografiya, 1960, Vol.5, No.3, pp.460-461
TEXTi The high temperature modification of Zr02 is cubic and has
.the CaF2 structure with a Zr coordination number of 8. The
coordination polyhedron is a cube. At room temperature this
structure is unstable and goes over to a monoclinic form with
dimensions very similar to those of the cubic form but with
P =-100'. The structure of this form was originally proposed by
K.Lonsdale but has now been worked out in detail by McCullough and
Trueblood (Acta Cryst. 12, 507, 1959). It is shown that the
coordination number of the Zr is lowered to 7 andthe way in which
this happens Is particularly neat. The structure of baddeleyite
can be considered as consisting of distorted square nets of oxygen
ions alternating with oxygen nets made up of squares and triangles.
The Zr ion touches 4 ions of the all square sheet and either 3 ions
or 4 tons of the mixed sheet according to the way it is displaced
in its own plane. The particular placing of the sheet thus gives
either the 8-coordination of the high temperature form or the

the monocrystalline RbBe 2F 5 plates for the study here described. The
crystals are biaxial, have the low refractive index (1~332) characteristic
of fluoberyllatea, and a very low birefringence (f~iO). They have perfect
cleavage along plane (001). The crystals have specific gravity 2.809,
are only slightly hygroscopic, and are subject to polymorphous transforma-
tionsduring heating The crystals are tr clinic, and one cell has the
parameters a - 7-98 1, b - 4.69 R, a - 6.12 1, 4 - 89040'. 0 - 910, y - 90027'

by a pseudohexagonal primitive cell. The presence of piezoelectric effect,
.together vith.statistioal analysis of the structural factors, rules out
all 8ymmetry groups except P1. The peaks of the Patterson syntheses
p(xz) and p(yz) are indistinct. Table I shows the coordinates of the
seven basal atoms (21 parameters) for the C1 cell. In the indisputable
BeF4 tetrahedrons the interatomic d1tances lie within the limits
Be-P - 1-43 - 1-48 t, F - Fx 2.33 - 2.41. In the RbF6 octahedrons, the
.Rb-F distances remain within the limits 2.82 -3 .06 2. The principal
structure of Rb difluoberyllate is, in the authors' opinion, a close-
packed brucite (phlogopite) layer of Rb octahedrons, oriented parallel
to (001). A hexagonal-patterned network of fluoberyllate tetrahedrons
extends between the layers of Rb octahedrons. In the fluoberyllate analog,
the di(meta) silicate model, there are no layers consisting of empty
polyhedrons. The layer of tetrahedrons oriented in two directions along
the pseudohexagonal axis may be conveniently called "one-and-a-half-
storied". The fluoberyllate network characteristic of RbBe2F 5 has the
same projection as all known silioio acid networks of the pa4udohexagonal

TEXT: There are 90 black and white point groups of which
31 permit the occurrence of a magnetic polarisation M and a
different 31 permit electric polarisation P. There are
10 groups common to the two categories, namely: 62121; 6; 3211~ 3;
42121; 4; 22121; 2; 21; 1. These are subgroups of oo 2121.
There are 3 further groups: mm'21; m; and ml, where the
vectors M and P are constrained to be perpendicular. In all
of the 10 groups ;ientioned first, except 21*and I where M
and P may make any angle with each other, ~1 and P must be
parallel. The 101 space groups corresponding to zhese 13 point
groups have been listed (Ref.4: N.N. Neronova, N.V. Belov,
Kristallografiya, v.4, 1959, 807-812). The above has assumed
that M and P belong to the same antisymmetry group,.which is
not necessarily the case. The relevant groups of double

ABSTRACT: This work is-an expansion'of an Idea from the author's book (Kristallo-
khimiya silikatov a krupny*mi kationami. Xzd-vo AN SSSR, M., 1961) that'silica
i and silicate radicals in natural and synthetic silicates play the role of "pro-
i tective envelopes" about other technologicarly more Important structural com-
pone ts in the crystal lattice. He states that the first step in this "develop-
mentle must be the formation of "piercing" silicate, chains
with somewhat the same

tural motif. This variety is attained by the simplest of means: by different
proportions of the basic silicate increments (the orthogroup [Si04] and the

necessarily tied up-with large cations. The orthogroup isneeded not only Vith,
small cations but also for more con4enient linking of basic diorthogroups. the
author points out a great number of structural arrangements, some known for a

now some altogether new ones , Nine new chains are diacussed and are illustrAted
