AnovelTetraazadioxomacrocyclicmetal Complex (M2L2) ofCu(II) have been synthesized. This complex was characterized by elemental analyses, molar conductance measurements, IR, Electronic absorption spectral and Luminescence spectral studies. The cyclic voltammograms of the macrocyclic complex shows the complex contain two metal ions. On the basis of molar conductance the complexes may be formulated as [Cu2(H2L2)(NO3)2 (H2O)2].xH2O. The complexes are insoluble inmethanol, acetonitrile, diethyl ether and chloroform but soluble in DMF, DMSO. The compound is stable both in the solid state and in solution.
