SPECTRAL AND THERMAL STUDIES ON COPPER(II) COMPLEXES OF ACENAPHTHAQUINONEMONO-(4-METHYLQUINOLINYL)HYDRAZONE

Cu(II) complexes of acenaphthaquinonemono(4-methylquinolinyl)hydrazone (AMH) of general composition [CuLX2] (where L =AMH; X =Cl, Br, I, OAc or NO3) With the exception of sulphato complex, where the composition is found to be [CuLSO4]2 have been synthesized and characterized by elemental analyses, magnetic moment measurements, conductivity measurements, IR, electronic and EPR spectral techniques and by thermal analysis. A planar geometry is indicated for all the complexes. TG curves show one step decomposition of complexes and formation of Cu2O at the end of the step.
