Synthesis and Spectral Studies of Thorium(IV) and Dioxouranium(VI) Complexes of Schiff Base Derived from Benzocain and p-Dimethyl Amino Benzaldehyde

Abstract

A new series of complexes of Th(IV) and UO₂(VI) with a Schiff base derived from condensation of benzocain and p-dimethylamino benzaldehyde having general composition ThX₄.nL (X = Cl^–, Br^–, NCS^– or I^–, n = 4; X ^– ClO₄^–, n = 6; X = NO₃^–, n = 2) and UO₂X₂.2L (X = NO₃^–, Br^–, I^–, NCS^– and CH₃COO^–) or UO₂X₂.4L (X = ClO₄^–, where L is Schiff base. The complexes were characterized on the basis of elemental analysis, molecular weight determination, magnetic moment, infrared and electronic spectral studies and conductivity measurements. In all the complexes, ligand behaves as monodentate neutral ligand which coordinate to metal by azomethine nitrogen.
