Synthesis Characterization and Antimicrobial Studies of Transition Metal Complexes of Bidentate Ligands

Abstract: A series of metal complexes of Ni (II), Co (II), Zn (II), Mn (II) and Fe (III), were prepared from Chalcones. The Chalcones were Prepared from 2'- Hydroxy acetophenones and 3,4-dimethoxy benzaldehyde. The synthesized metal complexes were characterized by molar conductivity, magnetic susceptibility, thermal analysis, FTIR, 1HNMR, and UV-Visible spectra. The analytical data of these complexes showed metal ligand ratio as 1:2. The physicochemical study supports the square planar geometry around Zn (II), Mn (II) and octahedral geometry around Co (II), Fe (III) and Ni (II) ions. The molar conductance values of metal complexes suggest their non electrolytic nature. Antibacterial and Antifungal activities of ligands and its metal complexes were performed in vitro against E. coli, S. typhi, S. aureus, B. subtilis and against various fungi like P. chrysogenum, A. niger, F. moniliformae, and A. Flavus.
