| Abstract: | The [Ir(NH3)5Cl]2[OsCl6]Cl2 binary complex salt has been prepared, and its structure was investigated by single crystal X-ray diffraction. Crystal data: a = 11.1901(13) Å, b = 7.9138(13) Å, c = 13.4384(18) Å; β = 99.640(3)°, V = 1190.0(2), space group C2/m, Z = 2, FW = 1099.47, d x = 3.068 g/cm3. Thermolysis products of [Ir(NH3)5Cl]2[OsCl6]Cl2, [Ir(NH3)5Cl][OsBr6], (NH4)2[OsCl6]x[IrCl6]1?x , and K2[OsCl6]x[IrCl6]1?x were studied by X-ray phase analysis; the unit cell parameters were refined, and the dependence of volume per atom (V/Z) on the composition of the Ir Os1?x solid solution has been plotted. |
