Syntheses, and Characterization of Complexes Containing Beta-lactam Group with some Transitional Elements and Study their Biological Activity

N. Ghufran Kareem and Mohammed Hamid Said


In this study, a novel azo-azomethine ligand [6[2-hydroxy-4-((3-nitrophenyl)diazenyl)-1-phenyl]imine penicillanic acid] [HNDIP] is synthesized from [2-hydroxy-4-((3-nitrophenyl)diazenyl) benzaldehyde]. And reflux with 6-aminopenicillin acid, this ligand was identified by UV-Vis, FTIR, 1H-NMR, C13NMR, and mass, and it was used to prepare new complexes with [Cu(II), Ni(II), Co(II), Zn(II), and Fe(II)] metal ions. These complexes were identified by FTIR, UV-Vis, molar conduct, magnetic sensitivity, and atomic absorption for all complexes, the reaction ingredients were observed to be ratio 1:2 (metal: ligand). The ligand, a tridentate with a single negative charge, was coupled with metal ions to form claw complexes, resulting in an octahedral shape. Finally, antibacterial effectiveness was determined for the ligand and complexes against two distinct bacteria strains (Pseudomonas and klebsiella). It was discovered that the ligand and its complexes have high inhibitory activity against bacteria (Pseudomonas and Klebsiella). As a result, the chemicals created may be feasible substitutes for routinely used drugs.
