In the present manuscript M⁺³ & M⁺² transition metal ions with biologically active chelating ligand 2(o^--hydroxyphenyl) benzthiazoline were synthesized and characterized from the studies viz., ir, uv-vis. spectra, magnetic susceptibility measurement. Physico-chemical studies suggested to be distorted octahedral and square planar coordination geometry in all cases of isolated M⁺³ & M⁺² complexes. Compounds 1-10 assayed for their vitro antimicrobial activities against four bacterial strains S. aureus, B. subtilis, E. coli P. aeruginosa, were found to be complexes are more noxious then ligand and also have significant biological properties for modification towards future drugs development as microorganism invalidate current antimicrobial agents effectiveness through many adaption and resistance. These complexes also have been found as efficient electron transfer agent in many biological processes.
