Synthesis, Spectral Characterization and Antimicrobial Screening of Co(II) and Ni(II) Complexes derived from (E)-1-((p-tolylimino)methyl)naphthalene-2-ol

The new coordination complexes of Co(II) and Ni(II) have been synthesized from Schiff base derived from 2-hydroxy1-naphthaldehyde and p-toluidine. The nature of bonding and the structural features of the Schiff base and its complexes have been deduced from elemental analysis, molar conductance, magnetic susceptibility measurements, IR, ¹H NMR, UV-Vis, and cyclic voltammetry studies. The spectral data of the complexes have revealed bidentate complexing nature of the Schiff base through azomethine nitrogen atoms and phenolic oxygen. The Schiff base and its metal complexes were screened for their antimicrobial activity. The complexes showed enhanced antimicrobial activity as compared to uncomplexed Schiff base.
