Synthesis and Conducting Properties of a New Mixed-valence Cu(I)-Cu(II) 1-D Coordination Polymer Bridged by Morpholine Dithiocarbamate
A novel mixed-valence Cu(I)-Cu(II) coordination polymer with an infinite one-dimensional (1-D) structure, [(Cu4CuI4)-Cu-I-I-II(Mor-dtc)(2)(CH3CN)(2)](n) (Mor-dtc(-): morpholine dithiocarbamate), was prepared and structurally characterized by X-ray diffraction. This complex consists of a mononuclear copper(II) unit of [Cu-II(Mor-dtc)(2)] and a tetranuclear Cu(I) unit of [Cu4I4(CH3CN)(2)]. It also shows semiconductive behaviors with a relatively small activation energy, which was revealed by impedance analysis.
