By altering their surrounding structure, metal ions enhance their capabilities through the use of heterocyclic moiety. The heterocyclic chelates having certain metals like zinc, cobalt, etc. have greater medicinal properties as like in metal-proteins which are present in oxygen carrier, involving electron transport reactions or in oxygen storage [3]. The electron density increases with the number of heteroatoms in the ligand, which in turn enhances the lyophilic nature of the metal chelates and diminishes the cell wall of pathogen [4,5]. Based on the aforementioned information, two significant heterostructures have been chosen for the current study, namely Synthesis and Characterization of Biopotent Transition Metal Complexes of Schiff Base 2-{(1)-1-[2-(1,3-Benzothiazol-2-yl)hydrazinylidene]ethyl}-6,10b-dihydro-3H-benzo[f]chromen-3-one and their Biological Evaluation

The electronic and magnetic susceptibility measurements suggest an octahedral geometry for all the complexes excepting Zn(II) complex which possess tetrahedral geometry. The results of thermogravimetric analysis showed that the synthesized complexes have thermal stability and con rms the absence of coordinated or lattice water molecules. The bio potency of all the compounds were investigated by studying the antimicrobial, antimycobacterial and cytotoxic activities. All the transition metal complexes were noticeably exhibited their inhibition properties against the tested microbes.
