Schiff-base coordination complexes with plutonium(iv) and cerium(iv)

Abstract

PuL₂ and CeL₂ (L = N,N′-bis[(4,4′-diethylamino)salicylidene]-1,2-phenylenediamine) have been synthesized, and characterized by single crystal X-ray diffraction, UV/vis/NIR spectroscopy, and cyclic voltammetry. These studies reveal the enhanced stabilization of Pu(IV) versus Ce(IV) with this Schiff base, and quasi-reversible redox behaviour only with the plutonium complex.
