  ABSTRACT

SPECTROSCOPIC STUDIES OF DIVALENT TRANSITION METALS COMPLEXES DERIVED FROM POTENTIALLY MONOBASIC BIDENTATE SCHIFF BASE AND BIDENTATE AZO DYE LIGAND

Complexes of bidentate ligands (1-(4-bromo-phenylazo)-naphthalen-2-ol (L1) and 1-[(4-bromo-phenylimino)-methyl]- naphthalen-2-ol (L2)) with life essential metal ions (Co(II), Ni(II), Cu(II) and Zn(II) ions) were synthesized and characterized by elemental analysis, molar conductance, electronic spectra, FT-IR, ESR and magnetic susceptibility measurements. The antibacterial and antifungal activities have been evaluated for the synthetic ligands. Disc diffusion methods were employed for antimicrobial assays against some pathogenic bacteria and fungi. The synthesized mixed ligand complexes exhibit higher antimicrobial activity than the free ligands.
