STRUCTURE AND THERMAL PROPERTIES OF [Rh(NH<sub>3</sub>)<sub>5</sub>Cl](WO<sub>4</sub>)<sub><i>x</i></sub>(MoO<sub>4</sub>)<sub>1-<i>x</i></sub> (<i>x</i> = 0, 0.5, 1)
The isostructurality of [Rh(NH<sub>3</sub>)<sub>5</sub>Cl](WO<sub>4</sub>)<sub><i>x</i></sub>(MoO<sub>4</sub>)<sub>1-<i>x</i></sub> (<i>x</i> = 0, 0.5, 1) complex salts is shown, and their thermal properties are compared. In a hydrogen atmosphere, transformations begin at <i>Т</i> ~ 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 (<i>V</i>/<i>Z</i>) of the atomic volume on the composition is presented. The thermal decomposition product [Rh(NH<sub>3</sub>)<sub>5</sub>Cl](MoO<sub>4</sub>) (<i>Т</i><sub>fin</sub> = 800°C) is shown to be the disordered Mo<sub>0.5</sub>Rh<sub>0.5</sub> solid solution (<i>а</i> = 2.757(2) Å, <i>с</i> = 4.428(4) Å, <i>P</i>6<sub>3</sub>/<i>mmc</i> space group).
