ABSTRACT:

A series of Cobalt(II), Nickel(II) and Copper(II) complexes have been synthesized with newly derived biologically active Schiff base ligand, 4-iso-propyl-1-methyl cyclohexane-2-one semicarbazone. The elemental analyses of the ligand as well as metal complexes indicate complexes having 1:2 stoichiometry of the type [M(IPMCS)2X2], where M = cobalt(II), nickel(II) and copper(II), IPMCS = 4-isopropyl 1- methyl cyclohexane semicarbazone and X = Cl-, Br-, I- and NO3-. The complexes have been characterized by IR spectral, electronic spectra, magnetic susceptibility and molar conductance data. The study of IR spectra of the ligand as well as metal complexes suggest linkage of metal ion through azomethine nitrogen and carbonyl oxygen atom of semicarbazone moiety. On the basis of electronic spectral and magnetic susceptibility values the complexes are proposed to be octahedral geometry. The molar conductivity also reveals that the complexes are non electrolytic in nature.
