Structural characterization of newly synthesized Ln (III) nitrate complexes with o-vanillin and p-toluidine derivatives


Author(s): Farheen Jahan

Abstract: The complexes of Ln (III) (Ln = Dy, Ho, Er, Tm and Yb) with Schiff base derived from o-vanillin and p-toluidine have been synthesized. The structures of these newly synthesized complexes were substantiated by elemental analysis, molar conductivities, infrared, and thermal analysis. The general molecular formula of the complexes are [LnL2(NO3)3]. The central metal Ln (III) ion in the complexes coordinates with both two ligands through four oxygen atoms of hydroxyl and methoxy groups and with three bidentate nitrates. Thus the coordination number of the metal complexes is ten. Thermal behavior of the complexes has been studied by TG and DTG. The residues after heating in thermal analysis correspond to metal oxide (Ln2O3).
