ABSTRACT

A new Schiff base, 2(E)-(5-hydroxy-2-methylphenylimino) methyl)-6-ethoxyphenol (EAP), has been synthesized from 3-ethoxysalicylaldehyde and 2-amino-4-methyl phenol. Metal complexes of the Schiff base were prepared from chloride salts of Ni(II), Co(II), Cu(II) and Zn(II) in alcoholic medium. Their structural data and antibacterial studies have been established on the basis of analytical, molar conductance, infrared electronic and magnetic studies, 1H-NMR, 13C- NMR, ESR and TGA. On the basis of color, magnetic moments and electronic spectral data, The geometries of Co(II), Ni(II), Cu(II), Zn(II) complexes have been assigned.

Keywords: Schiff base, 3-ethoxysalicylaldehyde, 2-amino-4-methyl phenol, Metal complexes, ESR, Antibacterial activity.
