Abstract

The synthesis and spectral analysis of Cu(II), Ni(II),Co(II) and Zn(II) complexes of 3-Chloro Vanillin Thiosemicarbazone (3-CVTSC) is reported. Their characterization using mass spectroscopy, elemental analysis, 1H NMR, 13C NMR, infrared spectroscopy,UV spectroscopy and Thermal Gravimetric Analysis as well as their antimicrobial properties were evaluated. In the formation of metal complexation, the metal is coordinated through the azomethine nitrogen and covalently to the sulfur atom.

Keywords: Synthesis, Thiosemicarbazone, Metal Complexes, Antimicrobial Activity.
