The experimental determination of Th(iv)/Th(iii) redox potentials in organometallic thorium complexes

Abstract

The first Th^IV/Th^III redox couple values have been determined experimentally using cyclic voltammetry (CV), which has been facilitated by the use of [ⁿBu₄N][BPh₄] as a supporting electrolyte in THF. Th(IV) and Th(III) metallocene compounds have been studied and their redox couple values are in the range of −2.96 V to −3.32 V vs FeCp₂^+/0.
