2D NMR Characterization of the La@C₈₂ Anion

Abstract

Mapping of bond connectivity in the carbon cage of the endohedral metallofullerene anion [[email protected]82-A]− (see picture, bottom) and definitive assignment of all the NMR signals were achieved for the first time by means of 2D INADEQUATE NMR spectroscopy measurements (see picture, top). The position of the encapsulated lanthanum atom (red sphere) was also confirmed by measurements of relaxation time T1 for the cage carbon atoms.
