Synthesis and Characterization of Thorium(IV) and Dioxouramum(VI) Complexes of a Schiff Base: Part 1.

Abstract

A new series of Th(IV) and UO₂(VI) with a Schiff base derived
from condensation of m-methyl aniline and p-(N,N'-dicyanoethyl)
amino benzaldehyde having general composition
ThX₄·nL (X = NO₃^-,  n = 2;  X = NCS^-,  n = 2 :  X = I^-,  n = 4;  X =
CIO₄^- ,  n = 6);  and UO₂X₂·2L (X = NO₃^-,  I^-,  NCS^- or CH₃COO^- )
and UO₂(CIO₄)₂·4L where L is the Schiff base.  The complexes were
characterized on the basis of analytical conductance molecular
weight and spectral studies. The Schiff base behaves as a neutral
monodentate ligand which coordinates to the central metal atom
through azomethine nitrogen.
