Abstract

A complex salt of tetraammineplatinum(II) perrhenate [Pt(NH3)4](ReO4)2 has been synthesized. Crystal data: a = 5.1847(6) Å, b = 7.7397(8) Å, c = 7.9540(9) Å, α = 69.531(3)°, β = 79.656(3)°, γ = 77.649(3)°, V = 290,19(6) Å3, space group \(P\bar 1\), Z = 1, d x = 4.370 g/cm3. The products of decomposition of [Pt(NH3)4](ReO4)2 in a hydrogen atmosphere were investigated using X-ray phase analysis. In definite temperature modes, these are Pt0.33Re0.67 solid solutions based on Re with hcp cell parameters a = 2.76 Å, c = 4.42 Å. The products of thermolysis obtained from other precursor complex salts containing both Pt and Re were investigated. Thus Pt0.75Re0.25 solid solution with a = 3.905(3) Å was obtained from (NH4)2[ReCl6]0.25[PtCl6]0.75.
