Synthesis, characterization and antibacterial activities of Cd(II) and Co(II) complexes of an ionic liquid based Schiff base

Sanjoy Saha, Rudra Prasad Roy

Abstract :

Cd(II) and Co(II) complexes of ionic liquid grafted Schiff base, 1–{2–(2–hydroxybenzylideneamino)ethyl}–3–methylimidazolium hexaflurophosphate, were synthesized and characterized by various analytical and spectroscopic methods such as elemental analysis, UV–Visible, FT–IR, 1H NMR, ESI–MS, TGA/DTG and magnetic susceptibility measurement. These studies indicated tetra coordinated tetrahedral geometry for the complexes. The Schiff base ligand and its complexes were tested for in vitro antibacterial activities to assess their inhibiting potentials against escherichia coli and lactobacillus spp. The results showed that the Cd(II) complex have higher antibacterialactivity then both the ligand and Co(II)complex.
