Inf rared absorption spectra B10.6/B144
oxalates containing Ti or Nb' however, showed two and three absorption i
'maxima, respectively, in these two ranges4. According to Zh. Lekont,
-(Infrakrasnoye iilucheniye (Infrared radintion), M4 1958), this proves that
the.titaniumi and niobium oxalates are-oomplax compounds. The spectra
showed that t~e water contained in the oxalates was orystallizatidn

both oxalate groups are coordinatively bound to Ti. There ar some
More bands in.Nb derivatives. Studies of the thermal stabflity of these
oxalates showed that two of the three oxalate groups are bound more loo"],Y,
nd,therefore are decomposed 'at lower temperatures, than the third. In
a
Ti compounds both.oxalate groups are decomposed at the same time. This
leads to the conclusion that in complex niobium oxalates only one oxalatei,
group is bound:doordinatively to Nb. General formulas suggested for the
Ti and Nb compounds investigatedi MeII [TiO(C 0 -nH 0, and

TEXT: The authors determined the dissociation constants of
internal complex compounds formed from salicylal-aminopyridine or
2+
its halogeno-derivatives and UO The bases used were:
2-salicylal-aminopyridine, 5 chior*o-, 5-bromo- and 5-iodo-2-salicyl-
aminopyridine. The dissociation constants of the complexes were
d
etermined by potentiometric titration with an alkali at pH values
I ranging from 3 to 6. The constants were calculated using
Bochkovals equation
