The reaction of copper(II) chloride with (NH4)2RuNOCl5 in the presence of ammonia or ethylenediamine (en) gives [CuLn][RuNOCl5] double complex salts with a nearly quantitative yield. The structures of the reaction products are determined by single crystal X-ray diffraction. The structure of [Cu(NH3)4(H2O)2][RuNOCl5] is formed by chains of alternating isolated cations and anions. The structure of [Cu(en)2][RuNOCl5] contains polymer chains due to the coordination of bridging chloride ligands along axial coordinates of square planar [Cu(en)2]2+. The thermal analysis and powder X-ray diffraction data show that the formation of Ru–Cu solid solutions during thermolysis of the studied compounds is complicated by the release of volatile copper(I) chloride at the early stages of thermolysis.
