Paper Title:
Synthesis and Characterization of Schiff Base with Bivalence Transition Metal Complexes Namely Cu, Co, Ni, Mn and Fe
  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 - 580nm region. This confirms the coordination of ligand with metal. The FT-IR shows a very strong band at 1616cm-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 3496 cm-1 is due to aromatic N-H stretching, It is noted that a broad band of the asymmetric and symmetric O-H stretching mode around the region 3400 cm-1 presumably due to H-O-H bending vibrations are not observed in the spectrum of complexes, which are indicating of the absence of the water molecule.
