摘　　要：A novel Cu（Ⅱ） complex has been prepared by means of self-assembly of CuCl2, 1-hexylimidazole L and oxalic acid （H2OX） in the presence of triethylamine, and structurally characterized by X-ray diffraction analysis. In complex 1, 1-D polymer chains are formed through pentacoordinated Cu（Ⅱ）, oxalate and bridging chlorine atoms. In the crystal packing of 1, the imidazole ring head-to-tail π-πstacking interactions exist between 1-D polymer chains and extend the 1-D polymer chains into 2-D supramolecular layers. The fluorescence emission spectra of L and 1 were described.A novel Cu（Ⅱ） complex has been prepared by means of self-assembly of CuCl2, 1-hexylimidazole L and oxalic acid （H2OX） in the presence of triethylamine, and structurally characterized by X-ray diffraction analysis.
