Schiff base complex of Zinc (II) ion has
been derived from benzoyl acetone, p-chlorobenzaldehyde, and o-anisidine.
The ligand, as well as metal complex, was characterized by elemental
analysis, UV-visible, magnetic moments, IR, 1H NMR, 13C NMR.
Non-electrolytic nature of zinc (II) complex was proved by the molar
conductance data. The antimicrobial activities of the ligand (L1)
and its zinc (II) complex against the bacterial strains such as
Escherichia coli, Bacillus subtilis, Staphylococcus aureus and the
fungus Candida albicans, Aspergillus niger, Aspergillus flavus
have been carried out. The effect of the substituent on the
biological activity of Schiff base and its complex was investigated.
Antibacterial and antifungal activity of the metal complex is
greater than the free ligand (L1) due to chelation and the presence
of the electron releasing methoxy group as a substituent in the
aromatic portion of the complex. |
