【 摘 要 】

A new mixed-valence Cu(I)–Cu(II) 1D coordination polymer, [Cu^I₄Cu^IIBr₄(Cy₂dtc)₂]_n, with an infinite chain structure is synthesized by the reaction of Cu(Cy₂dtc)₂ (Cy₂dtc⁻ = dicyclohexyl dithiocarbamate, C₁₃H₂₂NS₂) with CuBr·S(CH₃)₂. The as-synthesized polymer consists of mononuclear copper(II) units of Cu^II(Cy₂dtc)₂ and tetranuclear copper(I) cluster units, Cu^I₄Br₄. In the cluster unit, all the Cu^I ions have distorted trigonal pyramidal coordination geometries, and the Cu^I–Cu^I or Cu^I–Cu^II distances between the nearest copper ions are shorter than the sum of van der Waals radii for Cu–Cu.
