The first structural determination of a copper (II) complex containing the ligand [1-(4-((1H-benzo[d][1,2,3]triazol-2(3H)-yl)methyl)benzyl)-1H-benzo[d][1,2,3]triazole]

The reaction of the ligand [1-(4-((1H-benzo[d][1,2,3]triazol-2(3H)-yl)methyl)benzyl)-1H-benzo[d][1,2,3]triazole] (L) with CuCl2 in acetonitrile yields a dinuclear copper(II) complex [Cu2Cl4L2]center dot 2CH(3)CN (1.2CH3CN), which has been characterized by elemental analysis, powder and single crystal X-ray diffraction, thermal gravimetric analysis as well as IR, UV-Vis and EPR spectroscopy The crystal structure reveals that the metal coordination geometry is best described as square planar.
