Popis:	Complex salts [Ir(NH3)5Cl]x[Rh(NH3)5Cl]1−xMO4 (x = 0.5, 1; M = Mo, W) are synthesized and their thermal properties are studied. The crystal structures are determined for [Ir(NH3)5Cl]WO4 and [Ir(NH3)5Cl]MoO4. In the structures, the ions are linked by N-H...O hydrogen bonds, the shortest ones being 2.868(2)–3.422(2) A. and 2.860(4)–3.434(3) A. respectively. The thermal properties of the complex salts are studied in the hydrogen atmosphere and in hydrogen-helium mixtures. It is demonstrated that the final products are the mixtures of nanocrystalline powders of Ir and binary or ternary solid solutions with the hcp lattice.
