Аннотация: The fact of formation of the ternary solid solution of composition cis-[Pt(NH3)2Cln(NO2)2-n] is established. The conditions for its crystallization (including the crystallization in the mixture with the individual crystal cis-[Pt(NH3)2Cl2] and cis-[Pt(NH3)2(NO2)2] complexes) in a heterogeneous "liquid-solid" system at 20°C are deteПоказать полностьюrmined. The results of studies on the solubility, phase, and component compositions of the crystal products are presented. The kinetics of stepwise substitution of NO- 2 for Cl- in cis-[Pt(NH3)2Cl2] in aqueous solution at 25°C is investigated. The rate constants for the first step of substitution are calculated to be ks = (4.0 ± 0.3) ? 10-5 mol-1 l s-1 and ky = (4.58 ± 0.06) ? 10-3 mol-1 l s-1; as for the second step, its rate is found to be an order of magnitude lower than that of the first step. © 1996 MAEe Cyrillic signK Hay?a/Interperiodica Publishing.
