Abstract: Two new Co(II) and Cu(II) complexes from an imidazolium ionic liquid based Schiff base 1-{2-(2-hydroxy-5-nitrobenzylideneamino)ethyl}-3-ethylimidazolium tetrafluoroborate have been synthesized and characterized by different analytical and spectroscopic techniques such as elemental analysis (CHN analysis), UV-Visible, 1H-NMR, FTIR, Mass-spectra, Powder X-ray diffraction analysis, magnetic susceptibility measurements and molar conductance data. From these analytical results, tetra coordinated 1:2 metal-ligand stoichiometry is suggested for the both complexes. The molar conductance data of the complexes reveal their electrolytic nature (1:2). The synthesized complexes along with the ligand have been screened for in vitro antibacterial applications against gram negative and gram positive bacteria to assess their inhibition potentials. The complexes are proved to be very effective against the tested organisms.
