Abstract:
New Mn(II), Cu(II) and Zn(II) heterochelates were synthesize by reacting Semicarbazone,
Thiosemicarbazone and Antipyrine with 2 amino 3,5 dibromo benzaldehyde. All the
synthesized Schiff’s base ligands and their heterochelates were examined for their
spectroscopic and antimicrobial activities. The structures of Schiff’s base ligands were
confirmed by 1H NMR, IR, Mass, elemental analysis and their heterochelates were confirmed
by IR and FAB mass spectroscopy. All the Schiff’s base ligands and heterochelates were
screened for in-vitro biological study against Gram positive (Bacillus subtilis, S. Aureus) and
Gram negative (E. coli, Pseudomonas aeruginosa) microorganisms. The results confirmed
that transition metal based heterochelates have an immense potential and important for
further research work
