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.
