Pure samples of the species C60(Buckminsterfullerene) and C70(fullerene-70) have been prepared, and their structures characterised by their mass and 13C NMR spectra; the results indicate the existence of a family of stable fullerenes, thus confirming that carbon possesses a third form in addition to diamond and graphite.
