Abstract

The structure of an IPR-violated metallofullerene Sc₂Γ ₆₆ has been determined in the electron density level by the MEM/Rietveld method using synchrotron radiation powder data. The fundamental structure has been obtained by the Rietveld analysis. The cage structure of C₆₆ has been unambiguously identified as that of Isomer No. 4348. The obtained charge density by the MEM analysis shows that the encapsulated two Sc atoms form the covalent bonded Sc₂ dimer and that the charge density of dimer is overlapping with that of C₆₆ cage, indicating the existence of a covalent bond character between Sc₂ and the carbon cage.
