Department of Chemistry, A. P. S. University, Rewa-486 003, Madhya Pradesh, India E-mail : rnp64@ymail.com Fax : 91-7662-230260 Manuscript received 04 June 2009, revised 10 August 2010, accepted 03 October 2010 Five new mixed ligand copper(ll) complexes viz. Cu(PPS)(bipy)](CIO4)2 (1); [Cu(PPS)(phen)](CIO4)2 (2); [Cu(PPS)(dmp)](CIO4)2 (3); [Cu(PPS)(en)](CIO4)2(4); [Cu(PPS)(temed)](CIO4)2 (5) [PPS = phenyl(pyridyl-2-yl)methanoneN- phenylsemicarbazone, bipy = 2,2'-bipyridine, phen = 1,10-phenanthroline, dmp = 2,9-dimethyl-1,10-phenanthroline, en = ethylenediamine and temed = N,N,N',N'-tetramethylethylenediamine] have been synthesized and characterized by means of elemental analysis, magnetic susceptibility, X-band EPR electronic spectroscopy and cyclic voltammetry. The superoxide dismutase activity of the present complexes have also been measured
