摘要
Double complex [RuNO(NH3)4OH][PtCl4] (I) and [RuNO(NH3)4OH][PdCl4] (II) salts have been prepared and explored with TGA, IR spectroscopy, powder and single crystals X-ray diffraction. Crystal phases of I and II are isostructural (space group Cmc21) and have the following crystal chemical characteristics: a = 8.106 Å, b = 18.190(3) Å, c = 8.097 Å, V = 1194.0 Å3, Z = 4, ρcalc = 3.077 g/cm3 (I), and a = 8.116 Å, b = 18.135 Å, c = 8.062 Å, V = 1186.5 Å3, Z = 4, ρcalc = 2.600 g/cm3 (II). The product of thermal decomposition of I in inert and hydrogen atmospheres is a substitution solid solution Pt0.5Ru0.5 with the parameter of the FCC unit cell a = 3.856(3) Å. Thermolysis of II affords two-phase mixtures of limited solid solutions of the metals featuring Ru-based HCP and Pd-based FCC cells.
