The double complex salts [Ru(NH3)5Cl][PtCl6] (I) and [Ru(NH3)5Cl]2[PtCl6]Cl2 (II) were synthesized and studied by X-ray diffraction. They were found to be isostructural to the previously synthesized [Rh(NH3)5Cl][OsCl6] and [Ir(NH3)5Cl]2[PtCl6]Cl2. The thermolysis of the complexes in the atmosphere of hydrogen and helium was studied by the powder X-ray diffraction analysis.
The product of the salt I thermolysis is a single-phase solid solution Ru0.5Pt0.5 (a = 3.857(3) ?), the thermolysis of salt II results in a double-phase metallic powder.

The crystal structure of [Os(NH3)5Cl][ReCl6] has been refined by X-ray powder analysis: a = 11.645(3) Å, b = 8.3788(2) Å, c = 15.277(4) Å, β = 91.029(6)°, V = 1490(1) Å3, d x = 3.163 g/cm3, space group P21/m, Z = 4. The thermolysis product of the salt in a hydrogen atmosphere is a solid substitution solution Os0.5Re0.5: a = 2.753(2) Å, c = 4.366(3) Å, space group P63/mmc; coherent scattering region (CSR) is ~230 Å. 相似文献

Double complex salts [Ru(NH3)5Cl][OsCl6] and [Ru(NH3)5Cl]2[OsCl6]Cl2 were prepared and characterized. An X-ray diffraction study showed that [Ru(NH3)5Cl][OsCl6] is isostructural to the previously synthesized [Rh(NH3)5Cl][OsCl6]. The structure of [Ru(NH3)5Cl]2[OsCl6]Cl2 was solved by X-ray diffraction (a = 11.1849(8) ?, b = 7.9528(6) ?, c = 13.4122(9) ?; β = 99.765(2)°; V= 1175.75 ?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. 相似文献

According to the results of powder X-ray diffraction study of the complex salts of composition [M(NH3)5Cl][M"Cl4] (M = Ir, Rh, or Co and M" = Pt or Pd), the anhydrous salts crystallize in the orthorhombic system (space group Pnma) and are isostructural to the [Ir(NH3)5Cl][PtCl4] complex studied previously. The unit cell parameters of the resulting salts were refined. The metal powders, which were obtained by thermal decomposition of these salts under an atmosphere of hydrogen, were studied by powder X-ray analysis. 相似文献
