Popis: The crystals of {Rb11[Cu 2 1 ( H2O)2]}[Cu 15 1 Cl24(CuIICl6)] (I) formed in the RbCl-CuCl-H2O -( O2, C2H2 ) system were studied by X-ray diffraction analysis and ESR spectroscopy. The cell is monoclinic, space group B2/m, Z = 2, a = 24.787(3), b = 13.126(2), c = 11.318(5) A, γ = 122.36(1)ℴ (DARCH automatic diffractometer, γ(MoKgα). The crystal structure of compound I is a guest-host type structure consisting of the {[Cu 15 1 Cl24Cu11Cl6]13−}n anion layers oriented perpendicularly to the [010] direction and containing large octahedral cavities (edge length =12 A) with a discrete [ CuIICl6 ] octahedron lying inside the cavity. The Rb+ cations and the charged [Cu 2 1 ( H2O)2]2+ guest species lie between the anion layers. The effect of the nature of the guest on host structure formation is considered using compounds I and Rb11[Cu 15 1 Cl16Brd6CuIICl6 ) Cu-C=CH] as examples.
