A Cu(II) complex of tetra(3,5-diphenyl pyrazole) [Cu(C15H12N2)2Cl2]2 (1) was synthesized, and its structure was determined by single-crystal X-ray diffraction and further characterized by elemental analysis, NMR and IR. 1 belongs to the monoclinic system, space group P21/c with a = 13.3780(5), b = 15.1392(6), c = 15.5923(6) , β = 124.522(2)°, Z = 2 and V = 2601.86(17) 3. In 1, each Cu2+ ion is coordinated with two N atoms from two tetra(3,5-diphenyl pyrazole) ligands and three Cl- anions to give a distorted square-pyramidal geometry, which is further linked through edge-sharing bridging by Cl- anions to form a centrosymmetric dinuclear structure.
