VIBRATIONAL SPECTRA OF BENZALDAZINE AND SALICYLALDAZINE COMPLEXES WITH ZN(II) AND FE(II) IONS

ABSTRACT

The FT Infrared and FT Raman spectra of benzaldazine compound in the solid state in the wavenumber (1800–200 cm−1) are recorded. An assignment for nearly all fundamentals are proposed. for benzaldazine the complementarity of its IR and Raman spectra indicates that the molecular symmetry is most probably C_2h. The Zn(II) and Fe(II)-salicylaldazine complexes are synthesized and their structures are determined by elemental, thermogravimetric analysis, UV-Visible, IR and Raman spectral analysis. The two complexes are found to have the formula FeLċ3H₂O and Zn(HL)₂. It is found that Fe(II) coordinate via a tridentate manner whereas Zn(II) coordinate via tetradentate manner.
