Synthesis of Metal Complexes Fe(II), Co(II), Ni(II) of Monodentate Schiff Bases Derived from Aromatic Aldehyde

Abstract

A series of Schiff base ligands NPNA and newly NNNA have been synthesized in equimolar reaction of 1-Naphthylamine hydrochloride with or naphthalene-1-carbaldehyde. The synthesized Schiff bases were used for complexation with different metal ions like Fe(II), Co(II) and Ni(II) by using a molar ratio of ligand: metal as 1:1 and 2:1. The characterization of Schiff bases and newly formed complexes was done by UV–VIS, IR, spectral studies and analytical data. On the basis of the spectral studies show that the Schiff bases act as monodentate and an octahedral geometry has been assigned for Fe(II) and Ni(II) complexes and tetrahedral geometry for Co(II) complexes.

Keywords: Schiff bases, Fe(II), Co(II), Ni(II) complexes, spectroscopic studies.
