Endohedral fullerene compounds with isomeric carbon frameworks have been identified for the first time. The three stable isomers of Tm 2+ @C 82 2−were separated by HPLC, and characterized by cyclic voltammetry and by UV/Vis/NIR and 13 C NMR spectroscopy as probably having C 2 , C s , and C 3v symmetry (see picture).
