Isolation and Structural Characterization of the Endohedral Fullerene Sc3N@C78

Abstract

The unfavorable D3h isomer of the C78 fullerene cage is present in Sc3[email protected]78, an endohedral fullerene which has been prepared by the trimetallic nitride template process. The crystal structure of the fullerene–porphyrin adduct Sc3[email protected]78⋅[Co(oep)]⋅1.5 C6H6⋅0.3 CHCl3 (oep=octaethylporphyrin) shows that the scandium atoms are located over the centers of the [6,6] ring junctions of pyracylene patches on the inner surface of the fullerene (see picture).
