Schiff base thorium(iv) and uranium(iv) chloro complexes: synthesis, substitution and oxidation chemistry

Abstract

New tetradentate Schiff base chloro complexes of U(IV) and Th(IV) are prepared by salt metathesis approaches. These compounds undergo clean salt metathesis with NaN₃ to generate stable pseudo-trans azide compounds. The uranium dichloro complex also undergoes 2 e⁻ oxidation with excess NaNO₂ to generate the uranyl derivative. All classes of complexes are characterized by single crystal X-ray diffraction and NMR spectroscopy.
