Abstract
The binary complex salt [Rh(NH3)5Cl][PtBr6] was synthesized and studied by X-ray structural analysis. The crystallographic data are as follows: a = 12.013(2) Å, b = 8.401(2) Å, c = 15.999(3) Å, β = 91.13(3)°, V = 1614.3(6) Å3, space group P21/m, Z = 4, dx = 3.70 g/cm3, R = 0.086. The thermal decomposition of the salt in a hydrogen atmosphere is shown to produce a Rh0.5Pt0.5 solid solution with an FCC cell [a = 3.864(2) Å. The thermal decomposition of the salt in a helium atmosphere proceeds via the formation of metallic Pt and RhBr3 and finally results in a mixture of several solid solutions.
