Abstract: In this study, we report the synthesis of a novel Mannich base derived from maleichydrazide and its transition metal complexes . We tried this with maleichydrazide compound as a precursor and treated with formaldehyde and dicyclohexylamine. The so formed base was complexed with transition metals.The Mannich base ligand as well as the metal complexes were characterized by various physical methods.The structure of the synthesized compounds are confirmed by UV, IR, and 1H NMR spectroscopic techniques. The antibacterial activity of the ligands and the complexes were examined using different bacterias.
