ABSTRACT: In order to explain the effect of trans-influence in rhodium
complexes, the kiretics of the exchange rea ction in rhodium
compounds was examined. The reactions were carried out with the
rhodium,amines PyH[RhC TITHPyl and NH, [Rh(NO Fyj with the
14 1 Rh-NO 1 2)4 2
reactive coordinates Cl-Rh-Cl and ITO27 2'
In the interaction of rhodium amines with pyridine only an ex-
change of pyridine takes place by an.acid group which.is in a
trans-position to the other. The result Of 01030 exchtLnge re-

ABSTRACT: The electrolytic reduction of nitroso,compounds of ruthenium was
analyzed in order to ascertain the atate of valency of ruthenium
compounds. The method of electrolytic''reduction was applied
because no impurities are involved inAt. An investigation.was
carried out of the electrolytic reduction of compounds of~nitroao-
sulfate ruthenium, nitroso-nitrate ruthenium, nitroso-ooxalate
ruthenium and nitroso-acetate ruthenium. In the electrolytic
reduction of compounds of nitroso-oxalate ruthenium with the

formula H2 IRUNO (C204q three jumps aippear;in the reduction
curves. The first indicates the reduction of the NO-group, the
second indicates the reduction of Ru-(II) to Ru-(I) s-nd the third
indicates the reduction of Ru-(I) to Ru. The electrolytie're-

TITLE: On the Mechanism of the Inclusi'ons of Microquantities of

ABSTRACT: The mechanism of the coprecipitation of microquantities of the
cesium-iron-II-eyanide was investigat4d. The influence, of:the
nature of the cations on the solubility of the ferrocyanide
was investigated. The influence of the ratio of
Fe(CN)6 4- : Fe 3+ on the ooprecipitation of,cesium wab,investi-
gated as well. The authors conclude from the results that the
quantity of the coprecipitated cesiumidepends to an only small
extent on the ratio of the reagents and that the coprecipitation
of cesium is above all due to the formation of mixed crystals
or solid solutions, respectively. The investigations of the
influence of the various additions'on.the coprecipitation of
cesium as cesium ferrite cyanide showed that several cations

precipitation isothermal lines of the,cesium Berlin blue,were
plotted (Fig 2). Additional experimen'to were carried out in
order to explain the mechanism of the copr6cipitation of the
cesium Berlin blue. It was shown that in the case of an ad-
dition of cesium to finished Berlin blue sol the quantity of
the coprecipitated cesium is smaller,than in the case of,the
formation of sol in the case of the.presence of cesium, i. e.
the coprecipitation of cesium is much greater in the'formation
of Berlin blue sol. The coprecipitation of cesium with Berlin
blue was investieated as well in the precipitation in a homo-
geneous medium. The system ferrocyanide tartrate was used for
the precipitation in homogeneous medium. It was shown that the
coprecipitation of cesium with Berlin blue in the homoge neous
medium amounts to 99,97%, and in the:case of a rapid formation
of the precipitation to 99,86%. The coprocipitation,effect of
cesium with Berlin blue offers the possibility of a practical
application of this method for the c0precipitation of cesium
from diluted solutions. By means of this method of ion ex-
change the difference between the surface adsorption and the
coprecipitation was detected. Tho increase in the cesium

ABSTRACT: The above method for the co-precipitaiion of micro-quant1ties
of caebium showed-that co-precipitation is'not dependent on
caesium being contained in one or the"other of the two solutions.
The dependence of the constant according to V. G. Khlopin on
the amount of the solid phase which i6 formed on sudden pre-
cipitation was determined. The results are shown in table 2.
The values of the Xhlopin conatant D depend on the cuncentration
of iron (III) in the solution. Several rulaG governing the
formation of anomalous mixed crystal:~ werelconfirmed. By the
method of sudden co-precipitation the oo-precipitation isotherm
of caesium with Berlin blue was obtained. The experimental
data are in accordance with the equation by Kirgintsev

TITLE: Composition of thorium compounds with,malic acid
PERIODICALt Zhurnal neorganicheskoy khimiit v. 6,: no. 3, 1961, M-6010
TEXT: The systems thorium. nitrate - malic acid - w&~kerf thorium nitrat4
acid sodium malate - water, and thorium nitrate - sodium malate - water. were
studied by determining electrical conductivity, pH,.-,and by~potentiometrio
titrations. Two types of complex compounds of thorium with malic acid with
a ratio of the components of I : I and 1 : 2 were f6und. These complexes
exist in different forms, depending on the pH. Determination of the trans-
ference number disclosed that thorium migrates to the cathode in an acid
medium'at a ratio of the components of 1 : 1, and to the anode in a weakly
acid medium at a ratio of the components of 1 : 3~: It may be seen.from this
that in the compound with the composition I 1 1, thorium appears in the com-
plex as the cationg and in the compounds with the composition 1 t 2, it is
in a complex anion. The following thorium malates were sythesized*t

methods were use& for the production of basic thorium malate (ThOH)2Ma3 04H 20.-
methyl alcohol was added to an aqueous solution of,thorium nitrate and malic
acid. Basic thorium malate was obtained,in the form of a-khite. amorphous
precipitate which was washed out with water and acetone and then dried at~
1000C. In the second method, an aqueous solution of thorium. nitrate was ad-
ded to an aqueous solution of sodium malate in a ratio of Th(NO 3)4 : Na 2 Mal=
2 t 3. The composition of the compound with (ThOH )2Ma.l3 - 02 0 was deter-
mined by chemical analysis. This compound is insoluble inVater, alcohol,
benzene, acetone, and other organic solvents; it is decomposed when treated
with mineral acids. A stable complex compound with a ratio of the compo-
nents of 1 : 1 could not be isolated in an acid medium. At a ratio of tho
components Th(NO 3)4 ; Na-malate- I ; 3, and at PH - 4P a white precipitate
of the composition NaTh(OH)Mal 2 ' 6H20 results when methyl alcohol is added.
This compound is comparatively easily soluble in water$ but insoluble in

with sodium trihydroxy-glutaratel and with sodium bia-trihydroxy-glutarate
was studied by measuring the electrical conductivityp by potentiometric,
titrations and determinations of the transference numbers. It may be seen
from the results that thorium nitrate and trihydroxy -glutaric acid form
complexes with a ratio of the components of 1 t 1 and 1 t,2. The basic
thorium trihydroxy-glutarate has a ratio of the components

ABSTRACT: The mechanism of the coprecipitation of microquantities of the

nature of the cations on the solubility of the ferrocyanide
was investigated. The influence of the ratio of

gated as well. The authors conclude from the results that the
quantity of the coprecipitated cesiumidepends to an only small
extent on the ratio of the reagents and that the coprecipitation
of cesium is above all due to the formation of mixed crystals
or solid solutions, respectively. The investigations of the
influence of the various additions'on.the coprecipitation of

plotted (Fig 2). Additional experimen'to were carried out in
order to explain the mechanism of the copr6cipitation of the
cesium Berlin blue. It was shown that in the case of an ad-
dition of cesium to finished Berlin blue sol the quantity of
the coprecipitated cesium is smaller,than in the case of,the
formation of sol in the case of the.presence of cesium, i. e.
the coprecipitation of cesium is much greater in the'formation
of Berlin blue sol. The coprecipitation of cesium with Berlin
blue was investieated as well in the precipitation in a homo-
geneous medium. The system ferrocyanide tartrate was used for
the precipitation in homogeneous medium. It was shown that the
coprecipitation of cesium with Berlin blue in the homoge neous
medium amounts to 99,97%, and in the:case of a rapid formation
of the precipitation to 99,86%. The coprocipitation,effect of
cesium with Berlin blue offers the possibility of a practical

ABSTRACT: The above method for the co-precipitaiion of micro-quant1ties
of caebium showed-that co-precipitation is'not dependent on
caesium being contained in one or the"other of the two solutions.
The dependence of the constant according to V. G. Khlopin on
the amount of the solid phase which i6 formed on sudden pre-
cipitation was determined. The results are shown in table 2.
The values of the Xhlopin conatant D depend on the cuncentration
of iron (III) in the solution. Several rulaG governing the
formation of anomalous mixed crystal:~ werelconfirmed. By the
method of sudden co-precipitation the oo-precipitation isotherm
of caesium with Berlin blue was obtained. The experimental
data are in accordance with the equation by Kirgintsev

TEXT: The systems thorium. nitrate - malic acid - w&~kerf thorium nitrat4
acid sodium malate - water, and thorium nitrate - sodium malate - water. were
studied by determining electrical conductivity, pH,.-,and by~potentiometrio
titrations. Two types of complex compounds of thorium with malic acid with
a ratio of the components of I : I and 1 : 2 were f6und. These complexes
exist in different forms, depending on the pH. Determination of the trans-
ference number disclosed that thorium migrates to the cathode in an acid
medium'at a ratio of the components of 1 : 1, and to the anode in a weakly
acid medium at a ratio of the components of 1 : 3~: It may be seen.from this
that in the compound with the composition I 1 1, thorium appears in the com-
plex as the cationg and in the compounds with the composition 1 t 2, it is
in a complex anion. The following thorium malates were sythesized*t

methyl alcohol was added to an aqueous solution of,thorium nitrate and malic
acid. Basic thorium malate was obtained,in the form of a-khite. amorphous
precipitate which was washed out with water and acetone and then dried at~
1000C. In the second method, an aqueous solution of thorium. nitrate was ad-
ded to an aqueous solution of sodium malate in a ratio of Th(NO 3)4 : Na 2 Mal=
2 t 3. The composition of the compound with (ThOH )2Ma.l3 - 02 0 was deter-
mined by chemical analysis. This compound is insoluble inVater, alcohol,
benzene, acetone, and other organic solvents; it is decomposed when treated
with mineral acids. A stable complex compound with a ratio of the compo-
nents of 1 : 1 could not be isolated in an acid medium. At a ratio of tho
components Th(NO 3)4 ; Na-malate- I ; 3, and at PH - 4P a white precipitate
of the composition NaTh(OH)Mal 2 ' 6H20 results when methyl alcohol is added.

:ABSTRACT: The present worls was imdertaken to provide a verification of an earlier
!conclusion by the some authors that the stability of'cation~complexes of ovcar~oxy-i
Ilic acids with ions of rare earths in an acid medim as wall as the differential
ibetveen instability constants of these complexes for neighboring rare earths shou3Al
iincrease with decreasing distance between carboxyl groups. Applying pbysico-
chemical methods of preparative chemistry) interaction of praoeodpdua and neodyzium.
!nitrates vith oxymalonia acid vas studied for a vide pH ranpe. The earlier iugl~
gested mechanim of trivalent rare earths interaction with dicarbozylie oxyaoids~
has been confirmed. It has been established that the pH of the inadium has M do-
