Abstract

Eight chromium(II) complexes of type, [Cr(L)(H2O)x]·xH2O (where L= Schiff base ligand) have been synthesized and characterized on the basis of elemental analysis IR, 1H, 13C NMR, mass and electronic spectroscopy, magnetic and conductance measurements. The amino acid schiff base ligand behaved as a octadentate ligand. The probable structures of the chromium(II) complexes have been elucidated and also the chromium(II) complexes were screened for antibacterial activity, which showed a moderate to good activity against Gram-positive and Gram-negative bacteria.

Keywords

Phthalaldehyde, Amino acid Schiff bases, Chromium(II) compounds, antibacterial Activity.
