Rock solid : Fullerene‐encapsulated Li + (Li + @C 60 ) is an alkaline cation owing to the spherical shape and positive charge. Li + @C 60 crystallizes as a rock‐salt‐type crystal in the presence of PF 6 − . The orientations of C 60 (green; see picture) and PF 6 − (orange) are perfectly ordered below 370 K, and Li + (purple) hops within the cage. At temperatures below 100 K two Li + units are localized at two polar positions within each C 60 .
