A novel copper coordination polymer [Cu(C5H3N2O2)2] has been synthesized and it was characterized by elemental analysis,FTIR and X-ray diffraction single-crystal structure analyses.Crystal data: monoclinic,space group P2(1)/c,a = 5.0624(9) ,b = 15.414(3),c = 7.1110(13),β= 106.701(2)°,V= 531.48(16)3,Z=2,F(000) = 310,final R indices: R1 = 0.0216,wR2 = 0.0594.In the molecular structure,the central Cu ion is coordinated to two Pyrazine-2-carboxylic acid molecules.The pack structure shows that one dimension chain is formed by weak interaction among molecules.
