Abstract: A new Schiff base derived from 2-hydroxy-5-chloroacetophenone and S-methyldithiocarbazate and its coordination complexes with manganese(II), iron(II) cobalt (II), nickei(II), copper(II), zinc(II), cadmium(II) and oxovanadium(IV) have been synthesized. The resulting complexes have been characterized on the basis of their elemental analyses, molecular weight, infrared spectra, reactance spectra, magnetic susceptibilities, molar conductance measurements and thermogravimetric analysis. The Schiff base acts as a tridentate diabasic donor and coordinating through the deprotonated phenolic oxygen, thi oenolic sulphur and azomethine nitrogen atoms. The antibacterial activities of the ligand and its complexes have been screened against E. coli, S. aureus, Pr. mirabilis and S. typhi. Various kinetic and thermodynamic parameters have been evaluated from the thermograv imetric data and comparable values are obtained. Solid state conductivity of ligand and its complexes have also been measured from room temperature to about 473 K, in their pellet forms and the chelates are found to show semiconducting behaviour.
