Abstract: Complexes of Fe(III), Co(II), Ni(III), Cu(II) and Cr(III) with cyclic β-diketone ligand were synthesized by ultrasound irradiation and characterized by elemental analysis, conductometry, magnetic susceptibility, UV-Vis, IR, 1H-NMR, 13C-NMR, X-ray diffraction analysis of powdered samples thermal analysis, and screened for antimicrobial activity. The IR spectral data suggested that the ligand behaves as a bidentate ligand towards the central metal ion with an O-O,O-O donor atoms sequence. From the microanalytical data, the stoichiometry of the complexes 1:2 (metal : ligand) was found. The physico-chemical data suggested octahedral geometry for all these complexes. The thermal behavior (TGA/DTA) of the complexes were studied and kinetic parameters were determined by Horowitz- Metzer method. The powder X-ray diffraction data suggested a monoclinic crystal system for the Fe(III) and Co(II) complexes. The ligand and their metal complexes were screened for antibacterial activity against Staphylococcus aureus, B. subtilis and E. coli and fungicidal activity against A. niger and F. oxysporum.
