Recent Study on Synthesis, Characterization and Antimicrobial Activities of Some Transition Metal Complexes of Biologically Active Bidentate Ligands

A new solid complexes of Mn(II) and Fe(III) complexes with bidentate Schiff base ligand derived from
2-amino 4,6 dihydroxypyrimidine and P- chlorobenzaldehyde, P-nitrobenzaldehyde have been
reported. The ligand and its complexes were screened for their antifungal and antibacterial activity
against Aspergillus niger, Penicillium chrysogenum, Fusarium moneliforme and Aspergllus flavus and
Escherichia coli. Salmonella typhi, Staphylococcus aurious, B. subtilis. The result indicated that the
complexes exhibited good antifungal and antibacterial activities. The Schiff base commonly
coordinates through the oxygen atom of phenolic OH group and the nitrogen atom of azomethine
group, which is confirmed by IR spectral data. Further conclusive evidence of the co-ordination of the
Schiff bases with the metal ions was shown by the appearance of new bands due to n(M-N) and n(MO) in the metal complexes.
