Abstract

The Schiff base (BAP), benzilideneaminophenol was synthesized by refluxing ethanolic solutions of benzaldehyde and 2-aminophenol. Cu (II) and Co (II) complexes of the Schiff base with stoichiometry [M(BAP)2(H2O)2] have also been synthesized. The IR studies indicate that the Schiff base is acting as a bidentate ligand, and is co-ordinated to the metal through azomethine nitrogen and phenolic oxygen atom. IR spectra also indicate the presence of co-ordinated water. Octahedral geometry of these complexes could be confirmed from the electronic and NMR spectral data and magnetic moment values. The Schiff base acts as a promising candidate as an antimicrobial agent for E. coli and A. Niger.
