The copper(Ⅱ) complex with N(2-carboxyphenyl)salicylidenamine and imidazole ligands, Cu(C 14 H 9NO 3)(C 3H 4N 2) , was synthesized. The crystal belongs to orthorhombic, space group Pca2 1, with the crystal cell parameters: a=0.944 53(12) nm, b=1.122 78(9) nm, c=2.912 3(4) nm, V= 3.088 5(6) nm3 , M r=370.84, Z=8, R=0.036, wR=0.087, GOF=0.975. The copper(Ⅱ) ion lies in a distorted square-planar environment composed of two oxygen atoms, one nitrogen atom of the tridentate Schiff base ligand and one nitrogen atom of the imidazole ligand. The complex was also characterized by elementary analysis, IR, UV-Vis, TG and cycle voltammetry measurement.
