摘要:
Structures of three mixed solvates of copper halides: CuBr2 center dot DX center dot 2H(2)O, CuBr2 center dot 2DX center dot 2H(2)O, and CuCl2 center dot 2DX center dot 2H(2)O (DX is 1,4-dioxane) has been determined by the method of XRD on single crystals. The entry of both solvents into the first coordination sphere of the copper ion was proved. In spite of analogous composition, CuHlg(2)center dot 2DX center dot 2H(2)O solvates have different structures: the chain (Hlg = Br) and the island (Hlg = Cl) structures. The difference is caused by weakening donor power of acido ligands on passing from Br to Cl. DOI: 10.1134/S1070363211090052
