The endohedral structure of tri-metallofullerene Sc3@C82 is determined by the maximum entropy method (MEM) combined with the Rietveld method using synchrotron radiation powder data. The result reveals for the first time that Sc atoms are encapsulated in the form of a triangle Sc cluster inside the C3V−C82 fullerene. The charge state of the encaged trimer is also determined as Sc3+3@C3−82 from the MEM charge density. The Sc-Sc distance in the equilateral triangular Sc3 cluster is 2.3(3)Å
