Trans- [ICH2Co(en)2NH3] Complex was synthesized and characterized by chemical analysis, 1H, 13C NMR and Mass spectra. Pseudo first order reaction kinetics and binding studies of trans- [ICH2Co(en)2NH3] complex with imidazole, substituted imidazoles, histidine, histamine, glycine and ethyl glycine ester has been investigated using spectrophotometric technique. Equilibrium constants were determined as a function of pH at 25°c. Binding and kinetic studies were correlated based on basicity. steric hindrance. From the equilibrium data, it was found that the entering nucleophile participates in the transition state, thereby SN1 mechanism was proposed. The effect of the incoming ligands on the complex was studied by molecular mechanics. The binding property of this complex with DNA was observed using UV/Visible, Fluorescence studies. Antimicrobial property of this complex was also studied using E. coli bacteria.Keywords
