Abstract

Access to a chiral C(82) cage: Encaging a divalent samarium atom has provided access to an unexplored chiral cage of C(2)(5)-C(82) that has never been reported for trivalent M@C(82) or empty fullerenes. Inside this cage, a wandering Sm atom has been identified using crystallographic methods. In addition, electrochemical studies of Sm@C(2)(5)-C(82) have been performed to explore its oxidation properties (see figure).
