Synthesis, Spectroscopic Characterization and Thermal Studies of Some Transition Metal Complexes of Novel Schiff Base Ligand

RK Pawar, MA Sakhare and BR Arbad

The condensation of 4-chloro-2-amino phenol with 3-acetyl-6-methyl-(2H)pyran,2,4(3H)-dione (dehydroaetic acid (DHA) yielded 3-((E)-1-(5-chloro-2-hydroxyphenylimino)ethyl)-4-hydroxy-6-methyl- 2H-pyran-2-one. It’s Pd(II) and Ir(III) complexes were synthesized by stoichiometric ratio of combination. The ligand and their metal complexes were further characterized by elemental analysis, 1H NMR spectrum, mass analysis, conductivity measurement, UV/Visible and infrared spectroscopic studies. The ligand and it’s metal complexes were screened in vitro for antibacterial activity against Escherichia coli, salmonellatyphi and staphylococcus aureus and for antifungal activity against aspergillusflavus and candida albicans.
