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.
