Spectroscopic, thermal and voltammetric studies of crystalline complex trans-N,N′-bis(salicylidene)-1′,2′-cyclohexanediamine with Cu(II)

The dimeric complex, [C20H20CuN2O2]2, has been prepared and characterized by thermal analysis, IR spectroscopy and single-crystal X-ray diffraction techniques. The Cu atom in the binuclear complex exists in a distorted square-pyramidal configuration, defined by three O atoms and two N atoms. The crystal structure is stabilized by intermolecular C–H⋯O hydrogen bonding interaction. The electrochemical property of the complex was investigated in CH2Cl2 by cyclic voltammetry at 100 mV s−1 scan rate.
