Synthesis and characterization of uranium(VI) and thorium(IV) complexes with o-hydroxy N,N´-dimethylbenzylamine and o-carboxy N,N´-dimethylbenzylamine

Abstract

Summary Complexes of uranium(VI) and thorium(IV) with o-hydroxy N,N´-dimethylbenzylamine and o-carboxy N,N´-dimethylbenzylamine have been synthesized and characterized by elemental analysis, IR and 1H-NMR techniques. The coordination of metal ions with the ligand and their structures were established. The chemical and spectral properties revealed that uranium(VI) complexes have square bipyramidal structure for coordination number 6, and hexagonal bipyramidal structure for coordination number 8, whereas thorium(IV) shows bicapped square antiprism structure for coordination number 10.
