摘　　要：A new Zn（II） coordination polymer [Zn3（BTC）2（4,4＇-bpy）（CO）2]n （1, H3BTC = 1,3,5-benzenetricarboxylic acid, 4,4＇-bpy = 4,4＇-bipyridine） has been prepared through urothermal reaction of zinc nitrate hexahydrate with 1,3,5-benzenetricarboxylic acid and 4,4＇-bipyridine, and characterized by elemental analysis, IR spectroscopy, TGA and powder XRD, and its crystal structure was determined by single-crystal X-ray diffraction analysis. The title compound crystallizes in the monoclinic system, space group C2/c, with a = 10.262（3）, b = 18.838（5）, c = 15.083（4）/k, fl = 99.203（4）°, V = 2878.3（14） A3, C30H14Zn3N2O14, Mr= 822.54, Z = 4, Dc = 1.898 g/cm3,μ = 2.561 mm-1,F（000） = 1640, R = 0.0363 and wR = 0.0932 for 2828 observed reflections （I 〉 2σ（I））. X-ray analysis shows that the asymmetric unit of the title compound contains two crystallographically unique Zn（lI） atoms which are connected by BTC3- ligands and 4,4＇-bpy coligands to form a 3D framework with 1D channels. The solid luminescence of ligand and the title complex was also studied at room temperature.A new Zn（II） coordination polymer [Zn3（BTC）2（4,4＇-bpy）（CO）2]n （1, H3BTC = 1,3,5-benzenetricarboxylic acid, 4,4＇-bpy = 4,4＇-bipyridine） has been prepared through urothermal reaction of zinc nitrate hexahydrate with 1,3,5-benzenetricarboxylic acid and 4,4＇-bipyridine, and characterized by elemental analysis, IR spectroscopy, TGA and powder XRD, and its crystal structure was determined by single-crystal X-ray diffraction analysis.
