SYNTHESIS AND CHARACTERIZATION OF COMPLEXES OF SOME TRANSITION-METALSWITH BENZOYLDITHIOCARBAZATE

New transition metal complexes of benzoyldithiocarbazate (H2BDT) were synthesized. The structures of the complexes are proposed on the basis of elemental analyses, infrared spectra, electronic spectra, magnetic moments and TGA. Electronic and infrared spectral features of the com plexes, on comparison with those of the uncoordinated benzoyldithiocar bazate, indicated that benzoyldithiocarbazate behaves as a dibasic, te tradentate ligand in the enol form. The ligand coordinates to the meta l ions Cu(ll), Pb(II), Ni(II), Zn(II) and Cd(II) via the enolic oxygen , the nitrogens of hydrazide and the sulphur of thiolate and as a mono basic, tridentate ligand in the keto form to Cr(II).
