The endohedral natures of the metallofullerenes Y@C 82 and Sc 2 @C 8 4 are described based on synchrotron radiation powder diffraction experiments. For structural analysis, a combination of the maximum‐entropy method (MEM) and Rietveld refinement was employed to analyse the complicated powder pattern. The obtained MEM charge densities show a clear distinction of the endohedral natures of the mono‐ and dimetallofullerenes.
