摘　　要：The title polymeric complex [Cu(C_4H_2O_4)(C_(10)H_8N_2)]_n·2nH_2O wasprepared and its crystal structure was determined by X-ray diffraction methods. The crystal belongsto space group P2_1/c with cell dimensions of a = 1.0104(1), b = 1.9952(2), c = 0.7357(2) nm, β=98.38(2)° and Z = 4. The complex forms zig-zag chains along crystallographic axis c via Cu―O(car-boxyl) bond in the apical direction. Each repeated unit consists of a square pyramidal Cu( Ⅱ)centre with one maleate dianion and one 2, 2′-bipyridine forming a basal plane. Adjacent chainslink to each other by H-bonding between carboxyl groups and crystalline water. The distance of0.3482 run between parallel bipyridine rings shows a π- π stacking interaction. The title complexwas also characterized by IR, UV and ESR spectra.The title polymeric complex [Cu(C_4H_2O_4)(C_(10)H_8N_2)]_n·2nH_2O wasprepared and its crystal structure was determined by X-ray diffraction methods.
