Double complex salts [Ru(NH3)(5)Cl][OsCl6] and [Ru(NH3)(5)Cl](2)[OsCl6]Cl-2 were prepared and characterized. An X-ray diffraction study showed that [Ru(NH3)(5)Cl][OsCl6] is isostructural to the previously synthesized [Rh(NH3)(5)Cl][OsCl6]. The structure of [Ru(NH3)(5)Cl](2)[OsCl6]Cl-2 was solved by X-ray diffraction (a = 11.1849(8) angstrom, b = 7.9528(6) angstrom, c = 13.4122(9) angstrom; beta = 99.765(2)degrees; V = 1175.75 angstrom(3); space group C2/m; Z = 2). Thermolysis of the compounds under hydrogen and helium was studied. According to X-ray diffraction, nanosized metallic powders of the corresponding alloys are formed as the final products of thermolysis. The compositions of the obtained solid solutions are consistent with the phase diagram of the Ru-Os system.
