Rock solid: Fullerene-encapsulated Li+ (Li+@C60) is an alkaline cation owing to the spherical shape and positive charge. Li+@C60 crystallizes as a rock-salt-type crystal in the presence of PF6−. The orientations of C60 (green; see picture) and PF6− (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 C60.
