Abstract
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.
