A novel N,N'-dibenzyl-benzimidazolium tetrachlorocuprate(Ⅱ) complex, [C21H19N2]2[CuCl4], was synthesized and its crystal structure was determined by X-ray diffraction. It crystallizes in monoclinic system, space group P2/c, a=1.203 9(2) nm, b=0.975 0(2) nm, c=1.878 2(6) nm,β=114.12(2) , V=2.012 2(8) nm3. Its structure was identified by EA, IR and UV spectra and characterized by electrochemistry, thermal and magnetic property.The Cu(Ⅱ) atom of [CuCl4]2- has distorted tetrahedral coordination geometry. In the crystal structure, there are strong extensive C-H…Cl hydrogen bonds and π-π stacking interactions, which stabilized the crystal structure.
