Abstract: | Synthesis and Structure Investigations of Iodocuprates(I). XV Iodocuprate(I) with Solvated Cations: [Li(CH3CN)4] [Cu2I3] and [Mg{(CH3)2CO}6][Cu2I4] [Li(CH3CN)4][Cu2I3] 1 and [Mg((CH3)2CO)6][Cu2I4] 2 were prepared by reactions of CuI with LiI in acetonitrile and of CuI with MgI2 in acetone. 1 crystallizes orthorhombic, Pnma, a = 552.7(2), b = 1258.8(8), c = 2516(1) pm, z = 4. [Li(CH3CN)4]+ cations are located between rod packings of CuI4 tetrahedra double chains [(CuI2/2I2/4)2]? parallel to the axis. Short intermolecular anion/cation contacts were observed. The crystal structure of 2 (monoclinic, P21/n, a = 1840(2), b = 1059.2(2), c = 1879(2)pm, β = 112.94(4)°, z = 4) is built up by [Mg((CH3)2CO)6]2+ cations forming a simple hexagonal sphere packing. The binuclear anions [Cu2I4]2? occupy holes in the trigonal prismatic channels formed by the cations. |
