Antimicrobial Studies Of Synthesized ZincIi Schiff Base Complexes Of L-Arginine-2-Hydroxy-1-Naphthaldehyde And Glycine-2-Hydroxy-1-Naphthaldehyde

ABSTRACT The Schiff base ligands L-arginine-2-hydroxy-1-naphthaldehyde and glycine-2-hydroxy-1-naphthaldehyde and their ZnII complexes were prepared at room temperature. The infrared analysis proved that the ligands are bidentate and thus coordinated to the Zn II ion through their azomethine nitrogen atom and the oxygen atom of the carbonyl carboxylate ion COO-. From the UV analysis a four coordinate tetrahedral structure was proposed for the complexes. The antimicrobial studies carried out on Escherichia coli Staphylococus aureus Salmonella typhi and Candida albicans strains revealed that both the ligands and their complexes exhibit promising antimicrobial properties.
