The ¹³C NMR spectra were measured for three isomers of Tm@C₈₂, which is one of the divalent metallofullerenes. The molecular symmetries were determined for each isomer: isomer I has C_s symmetry, isomer II has C₂ symmetry, and isomer III has C₂_v symmetry. Moreover the cage structure of Tm@C₈₂(III) was found to be C₈₂(9). As a result, it was revealed that Tm@C₈₂(III) has a cage identical to that of La@C₈₂, which is one of the trivalent metallofullerenes.
