摘　　要：A new copper（Ⅱ） coordination polymer [Cu2（C7H5N4）2（3-C6H5NO2）2]n（1） has been hydrothermally synthesized with copper hydroxide, 3-（pyridin-2-yl）-1,2,4-triazole（Hpt） and 3-pyridinecarboxylic acid（3-PCA）. It crystallizes in the monoclinic space group C2/c, with a=16.854（2）, b=7.8616（8）, c=20.630（2） , β=111.126（2）o, V=2549.7（5） 3, Dc=1.723 g/cm3, Z=8, F（000）=1336, the final GOOF=1.065, R=0.0380 and w R=0.0972. The whole molecule consisting of two copper ions are bridged by two μ2-η1：η0-3-（pyridin-2-yl）-1,2,4-triazole anions. The coordination environment of Cu（1） ion is CuO2N4, giving a distorted octahedron geometry. 1 exhibits antiferromagnetic interaction, and the electron transfer of 1 is irreversible in electrode reactions and the TG analysis shows that 1 is stable below 235 ℃.A new copper（Ⅱ） coordination polymer [Cu2（C7H5N4）2（3-C6H5NO2）2]n（1） has been hydrothermally synthesized with copper hydroxide, 3-（pyridin-2-yl）-1,2,4-triazole（Hpt） and 3-pyridinecarboxylic acid（3-PCA）.
