	Abstract
	Sn(II) and Pb(II) complexes of two symmetrical Schiff bases have been synthesized and characterized by various physico-chemical studies. The spectroscopic data(IR,¹H NMR) indicates coordination of metal ions through azomethine nitrogen and acetate/chloride ions. Mass spectrum explains the successive degradation of the molecular species in solution and justifies M:L:: 1:1 complexes. Molecular structure of the complexes has been optimized by MM2 calculations and suggests a tetrahedral geometry. Kinetic and thermodynamic parameters were computed from the thermal data using Coats and Redfern method, which confirm first order kinetics. The bio-efficacy of the ligands and their complexes has been examined against the growth of bacteria in vitro to evaluate their anti-microbial potential.
