Preparation and Characterization of Rare Earth Complexes of Schiff Base Derived from o-Vanillin and p-Toluidine

Abstract

Abstract: The rare earth complexes of Schiff base derived from o-vanillin (2-hydroxy-3-methoxy-benzaldehyde) and p-toluidine (LnL₂Cl· 2H₂O)Cl₂(Ln: Ce, Pr, Nd, Sm, Eu, Gd, Dy, L. Schiff base) have been prepared and characterized. The complexes consist of a centre rare earth ion, two coordinated Schiff bases, one coordinated chlorine ion, two coordinated water and two non-coordinated chlorine ions. The infrared spectra, molar conductances, and thermal analysis of the complexes were measured. Their stabilities were also discussed.

Key words: o-Vanillin, Schiff base, Rare earth complexes
