A new semiconducting 1D Cu(i)–Cu(ii) mixed-valence coordination polymer with Cu(ii) dimethylpiperidine–dithiocarbamate and a tetranuclear Cu(i)–Br cluster unit†
Abstract
A novel mixed-valence coordination polymer [CuI4CuIIBr4(dmpip-dtc)2(CH3CN)]n (dmpip-dtc = dimethylpiperidine–dithiocarbamate) with an infinite one-dimensional structure was synthesized and structurally characterized using X-ray diffraction. The electronic properties of the coordination polymer were investigated by UV-vis-NIR spectroscopy. Impedance measurement results demonstrated that this complex has a narrow bandgap, inducing semiconducting behavior.
