Structure and Thermal Properties of [Rh(NH3)5Cl](WO4)x(MoO4)1s-x (x = 0, 0.5, 1)

The isostructurality of Rh(NH₃)₅Cl](WO₄) _x (MoO₄)_1s-x (x = 0, 0.5, 1) complex salts is shown, and their thermal properties are compared. In a hydrogen atmosphere, transformations begin at T ∼ 200°C. According to the powder XRD data, the phase composition of the end products is markedly different. For the Rh—Mo system, the dependence (V/Z) of the atomic volume on the composition is presented. The thermal decomposition product Rh(NH₃)₅Cl](MoO₄) (T _fin = 800°C) is shown to be the disordered Mo_0.5Rh_0.5 solid solution (a = 2.757(2) ?, c = 4.428(4) ?, P6₃/mmc space group).
