Synthesis and Characterization of the Complexes of N-Dimethylaminomethyl Isatin β-Thiosemicarbazone with Cobalt, Nickel, Copper, Zinc, Mercury and Iron Chlorides

Abstract

Abstract Complexes of N-Dimethylaminomethyl-isatin β thiosemicarbazone (C12H15N5OS) with Co(II),Ni(II),Cu(II), Hg(II) and Fe(III) have been prepared. The complexes were characterized by elemental analyses, molecular weight determination, conductance, magnetic moment measurement, electronic and i.r spectra. Complexes are of general formula M [L]2 where M = Co(II),Ni(II),Cu(II),Zn(II) and Hg(II) and M [L]2Cl where M = Fe(III). Cobait, copper, zinc and iron complexes are octahedral whereas nickel and mercury complexes are tetrahedrally coordinated. The i.r. spectra of the complexes indicate metal ligand bonding through sulphur, hydrazinic nitrogen and ketonic oxygen at ons of the ligand.
