Abstract

Sc2C2@C-82(II) and Sc2C2@C-82(III) have been synthesized and chromatographically isolated and characterized by using UV-Vis-NIR absorption spectroscopy. Solid-state C-13 and Sc-45 NMR on Sc2C2@C-82 metallofullerenes provide the rotational activation energy of Sc atoms encapsulated in C-82 fullerenes which is lower than that in solution due to crystal field effects on the rate of the rotation.
