A Scandium Carbide Endohedral Metallofullerene: (Sc2C2)@C84

Abstract

Not Sc2@C86 but Sc2C2@C84: that is the conclusion of 13C NMR spectroscopic and synchrotron X-ray powder diffraction studies on a new metallofullerene obtained by arc discharge of Sc2O3/graphite rods. The picture shows a schematic representation of the deduced structure, in which the novel scandium carbide cluster Sc2C2 is encaged in D2d-C84.
