Abstract

Electrochemical behaviours of UO₂(β-diketonate) ₂DMF, UO₂(trop)₂DMF and UO ₂(sap)(DMF)₂, (DMF, N,N-dimethylformamide; β-diketonate, thenoyltrifluoroacetonate(ttfa); benzoyltrifluoroacetonate(btfa) and dibenzoylmethanate(dbm); trop, tropolonate and sap, 2-salicylidenaminophenolate) complexes in DMF solution containing tetrabutylammonium perchlorate as a supporting electrolyte have been investigated by cyclic voltammetry. These uranyl(VI) complexes were found to be quasi-reversibly reduced to U(V) species. The formal redox potentials (E ⁰, versus ferrocene/ferrocenium) for U(VI)/U(V) couples were determined to be -1.176 V for UO₂(ttfa)₂DMF, -1.183 V for UO₂(btfa)₂DMF, -1.461 V for UO₂(dbm) ₂DMF, -1.456 V for UO₂(trop)₂DMF and -1.585 V for UO₂(sap)(DMF)₂ complex.
