ResumoCyclic-(CV), differential pulse (DPV), and Osteryoung square wave voltammograms (OSWV) have been performed on the pure fullerenolanthanides, two [email protected]82 isomers and [email protected]82, for the first time. Five reversible reduction and one reversible oxidation processes were observed for [email protected]82-A (major isomer). The first oxidation potential is approximately equal to that of ferrocene, indicating that [email protected]82-A is a good electron donor. The CV of [email protected]82-B (minor isomer) is similar to that of the major isomer, but the first oxidation potential is cathodically shifted by 0.14 V. The electrochemistry of [email protected]82 resembles those of the [email protected]82 isomers. The first oxidation and reduction potentials of [email protected]82 are anodically shifted by 0.03 and 0.08 V, respectively, relative to those of the major isomer of [email protected]82. These small anodic shifts could be attributed to the difference of the ionic radii of Y3+ and La3+. Fullerenolanthanides studied in the present work are stronger electron acceptors than empty fullerenes such as C60, C70, C76, C82, C84, and C86.
