Synthesis and Characterization of Thorium(IV) and Uranium(IV) Corrole Complexes

“…Cyclic voltammetry (CV) experiments show that the thorium corrole undergoes two reversible processes ( E 1/2 = 124 and 616 mV; Figure ). Additionally, there is an irreversible oxidation at 1.32 V and an irreversible reduction at −1.81 V. Thorium(IV) is not expected to display any redox behavior within the potential range discussed here . Therefore, these features may confidently be regarded as ligand-based processes, arising from changes in the macrocycle electronic structure due to both the electron-withdrawing effect of the metal center and the extreme distortion of the corrole ring from planarity upon binding to the actinide.…”
