SYNTHESIS AND SPECTRAL STUDIES OF 2-METHYLPIPERAZINEDITHIOCARBAMATO COMPLEXES WITH SOME 1ST ROW TRANSITION-METALS

New complexes of Cr(III), Fe(III), Co(II), Ni(II) and Cu(II) with 2-methylpiperazine-dithiocarbamate (2-Mepipzdte) have been synthesised and characterised by elemental analysis magnetic ir, electronic and esr spectral data. The ligand exhibits bidentate nature and the complexes are soluble only in strongly coordinating and highly polar solvents like DMF and DMSO. From the esr spectral data of copper(II) derivative the bonding parameters (<2, beta(1)2 and beta(2)) have been calculated and which indicate strong metal-ligand covalency.
