Trifluoromethylated derivative Sc 3 N@C 80 (CF 3 ) 2 exhibits three reversible reductions and two reversible oxidations, and affords the facile generation of the paramagnetic monocation, monoanion, and trianion in solution, which can be characterized by ESR spectroscopy. In their Communication on page 4721 ff., A. A. Popov, J. P. Phillips, S. Stevenson, S. H. Strauss, O. V. Boltalina, L. Dunsch et al. reveal a spin‐density shift from the fullerene cage to the Sc 3 N cluster on going from the cation to trianion, with a high spin density on one Sc atom in the latter.
