Treatment of HCbpBr (Cbp=N-(4-carboxybenzyl)pyridinium) with CuCl2·2H2O afforded mononuclear complex [CuCl2 (H2O)2] [(Cbp)2]·H2O(1). Compound 1 was characterized by elemental analysis, IR spectra and X-ray crystal structure analysis. Compounds 1 crystallizes in the monoclinic space group P2(1)/c, a=9.2537(19), b=14.750(3), c=22.046(4) , V=3009.0(10) 3 , Z=4, μ=0.946mm-1 , Dc =1.357Mg/m 3 , T=291(2) K, C26H28Cl2 CuN2O7 , Mr =614.95, F(000) =1268, S=1.046, R=0.0854, wR=0.1369. In the compound 1, the Cu atom is coordinated by two Cl atoms and two O atoms from two H2O molecules, thereby forming a distorted tetrahedron coordination geometry. The carboxyl acid ligand exhibits as its zwitterionic form. The coordinated H2O molecules have hydrogen bonding interactions with the guest H2O molecules and the O atoms from the acids.
