Abstract
We report the synthesis, isolation, and characterizations of the novel trimetallofullerene Sm3@I(h)-C80. Importantly, the experimental X-ray structure of Sm3@I(h)-C80 verified for the first time that three metal atoms can be stabilized in a fullerene cage without a nonmetal mediator. Furthermore, computational studies demonstrated the electronic features of Sm3@I(h)-C80, which are similar to that of theoretically studied Y3@I(h)-C80. Electrochemical studies of Sm3@I(h)-C80 showed a major difference from those of the well-studied isoelectronic species Sc3N@I(h)-C80 and La2@I(h)-C80.
