A novel ligand was synthesized from terephthalaldehyde and o-phenylene diamine and treated with coumarin derivative to form a New Schiff base. Co(II), Ni(II) and Cu(II) complexes of the ligand were synthesized. 1HNMR and LC-MS mass spectrometry studies were done. Antimicrobial studies were performed for the ligand and its metal complex with E.Coli and was found to be active. The ligand can be further modified and studied for its antimicrobial action in the future.
