Synthesis and Characterization of Some Transition Metal Complexes Derived from 5-Nitro salicylaldehyde and p-Anisidine

Abstract

Transition metal(II) complexes of the type ML₁ [where M = Co(II), Ni(II), Cu(II) and Zn(II), L₁ = Schiff base derived from 5-nitro salicylaldehyde and p-anisidine] have been prepared characterized by elemental analysis, molar conductivity, IR, electronic spectra, magnetic susceptibility studies and X-ray diffraction spectra. Molar conductivity measurements indicate that the complexes are non-electrolytic in nature. The analytical data indicates that the metal to ligand ratio in all the complexes is [1:2]. IR spectral data suggests that the ligand behaves as a bidentate O, N donar system. Magnetic susceptibility measurements indicates paramagnetic behaviour of all the complexes except Zn-complex. X-ray diffraction studies suggests monoclinic crystal system for these complexes.
