Haque, T. M. A. published the artcileSynthesis, characterization and antibacterial activity of Zn(II) and Cd(II) Schiff base complexes with monovalent bidentate ligand, COA of Formula: C10H9NO4S, the publication is Asian Journal of Biochemical and Pharmaceutical Research (2016), 6(2), 63-70, database is CAplus.
A new Schiff base, N (4-dimethylamino benzylidene) amino-2-naphthol-4-sulfonic acid has been synthesized from 4-dimethylamino benzaldehyde and 1-amino-2-naphthol-4-sulfonic acid. Zn (II) and Cd(II) complexes of the above ligand was synthesized as well. The chem. structures of the Schiff-base ligand and its metal complexes were confirmed by IR, UV-VIS, 1H NMR, elemental anal., molar conductance and m.p. The anal. data of the complexes show the formation of 1:2 metal to ligand ratio with the formula [ML2], where M represents Zn(II) and Cd(II) ions, and L represents the Schiff base ligand resp., diamagnetic nature and a tetrahedral geometry around the metal ion. The results suggest that the Schiff base is a monovalent anion with bidentate ON donor atoms of the phenolic oxygen and the azomethine nitrogen atoms. The complexes were non-electrolytes in DMSO solvent (DMSO). Antibacterial activity of prepared Schiff′s base and its metal complexes were studied on gram pos. Staphylococcus aureus and gram neg. Escherichia coli. It was found that the Schiff′s bases under study were considered inhibitors for bacterial growth with variation extent.
