A Cu(II) complex of tetra(3,5-diphenyl pyrazole) [Cu(C(15)H(12)N(2))(2)Cl(2)](2) (1) was syn-thesized, 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 P2(1)/c with a = 13.3780(5), b = 15.1392(6), c = 15.5923(6) angstrom, beta = 124.522(2)degrees, Z = 2 and V = 2601.86(17) angstrom(3). In 1, each Cu(2+) 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.
