Synthesis, Characterization and Antimicrobial Studies of Some Transition Metal Complexes of Schiff Bases

摘要

A series of transition metal complexes of Cu(II), Co(II), Ni(II), Zn(II), Cd(II) and Hg(II) with a bi dentate ligand, bis (2-Pyridyl Carboxyl aldehyde) ethylene diamine prepared by the condensation of 2-Pyridyl carboxyl aldehyde and ehtylene diamine. The metal complexes has been characterized on the basis of elemental analysis, conductance and magnetic data, infrared, H1NMR data. From elemental analysis, the complexes has been found to be 1:2 (metal: ligand). According to this data, we propose an octahedral geometry for metal (II) complexes. The ligand and metal complexes were screened for their physiological activities against E.coli, Staphylococcus aureus, Bacillus subtilis and Salmonella typhi.
