(IV) 2[Sn()6] - (IV) 2[Pb()6] Kosenkova Olga Vladimirovna (Russia) Synthesis, structure and acid properties of hydrated dioxides of the elements of germanium and titanium subgroups The investigation deals with the synthesis of compounds of elements of the germanium and titanium subgroups: TiO22, GeO20,12, SnO21,752, ZrO22,52, HfO22,32, PbO20,12, Rb2[GeO2(OH)2] 22, Rb2[GeO2(OH)2], Rb2GeO3, 2[Sn()6], 2SnO3, Na2[Pb(OH)6], Na2PbO3, 2[Pb(OH)6], 2PbO3 and the study of their physical and chemical properties. A comparative and systematic investigation of acid - base equilibrium emerging on the hydrated dioxide - electrolyte was carried out for the first time.

The constants of acid - base equilibrium were calculated. The solubility and composition of solid phases in the systems ͖SnO21,752Ζ2 ͖ PbO22 at 25C were studied. The designs of the thermolysis were suggested.

Crystal structures of Rb2[GeO2(OH)2]22 were studied.
