This paper describes the first electrochemical data for a polymetallic endohedral metallofullerene. The voltammetric behavior of Sc{sub 3}@C{sub 82} resembles that for La@C{sub 82} and Y@C{sub 82}, indicating that the identity of the metal does not influence dramatically the energies of the metallofullerene molecular orbitals. The three Sc atoms, however, transfer more electrons from the encapsulated metals to the cage than the monometallic counterparts, accounting for the differences in the voltammetry for Sc{sub 3}@C{sub 82}. The similarity of the voltammetry of Sc{sub 3}@C{sub 82} with that of the monometallic fullerenes suggests that Sc{sub 3}{sup +4}@C{sub 82}{sup 4-} may describe the formal charges on the Sc trimer and the C{sub 82} cage of these species. Metallofullerene electronic structure and physical properties should be better understood as more metallofullerenes become available for investigation. 31 refs., 1 fig., 1 tab.
