Synthesis, Physico-Chemical Characterization and Antibacterial Studies of New Fe(III) and Cr(III) Complexes with an Ionic Liquid-Supported Schiff base ligand
Abstract
An ionic liquid-supported Schiff base 1-{2-(2-hydroxy-5-bromobenzylamine) ethyl}-3-ethylimidazolium tetrafluoroborate and its Fe(III) and Cr(III) complexes were prepared and characterized by various analytical and spectroscopic methods such as elemental analysis, UV-Visible, FT-IR, 1H NMR, Mass-spectra, TGA/DTG, molar conductance and magnetic susceptibility measurements. Based on these spectral studies octahedral geometry was proposed for the both complexes. Molar conductance of the complexes showed their electrolytic nature. The Schiff base ligand and its complexes were tested for in vitro antibacterial activities against gram positive and gram negative bacteria to assess their inhibition potentials. Cr(III) complex showed higher activity than the Fe(III) complex against the tested bacteria S. aureus and E.coli.
