A new copper(Ⅱ) coordination polymer [Cu_2(C_7H_5N_4)_2(3-C_6H_5NO_2)_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 μ_2-η~1:η~0-3-(pyridin-2-yl)-1,2,4-triazole anions. The coordination environment of Cu(1) ion is CuO_2N_4, 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 ℃.
