Synthesis and Characterization of Ligand and its Metal Complexes

Abstract:

A series of metal complexes have been synthesized by the reaction of Schiff base with metal (II) salt solution. The complexes were characterized by UV and FT- IR studies. The study reveals that the geometry of the complexes were octahedral. The electronic spectra of these complexes show a strong absorption band in 550 – 580 nm region. This confirms the coordination of ligand with metal. The FT-IR shows a very strong band at 1606cm^-1 assigned to C=N stretching vibration. It is shifted to lower wave number because of the complex formation, suggesting that coordination of the Schiff base groups through N- atoms with the metal ion. The band at 3056cm^-1 is due to aromatic O-H stretching, the sharp peak at 750 cm^-1 and 688 cm^-1 are due to halogens substituted in the para position.
