A. Sygula et al., The first crystal structure characterization of a semibuckminsterfullerene, and a novel synthetic route, CHEM COMMUN, (24), 2000, pp. 2439-2440
Tetrabromosemibuckminsterfullerene 6, obtained by a novel synthetic route,
is converted to the tetramethyl derivative 7; X-ray crystal structure deter
mination of the latter reveals a highly nonplanar, bowl-shaped molecule wit
h solvating CCl4 molecules separating the hydrocarbon moieties.
