New mixed-valence coordination polymers [(Cu5CuI5L2)-Cu-I-I-II(C2H5CN)(2)]center dot CHCl3)(n) (L = piperidinedithiocarbamate and hexamethyl-dithiocarbamate) with isomorphous infinite one-dimensional (1D) structures were prepared and structurally characterized via X-ray diffraction. These complexes comprised a mononuclear Cu(II) unit, (CuL2)-L-II, and a pentanuclear Cu(I) cluster unit, (Cu5I5)-I-I(C2H5CN)(2). Impedance measurements demonstrated that these Cu(I)-Cu(II) mixed-valence 1D coordination polymers displayed semiconducting behavior with low conductivities. (C) 2013 Elsevier Ltd.
