| Abstract: | The crystal and molecular structures of the bromofullerene solvates C60Br6·0.5C6H5Cl·0.5Br2, C60Br8·1.5(o-C6H4Cl2), C60Br8·Br2, C60Br8·0.5C6H5Br·0.5Br2, and C60Br24·2Br2 have been determined by single crystal X-ray diffraction. The molecular species C60Br6, C60Br8, and C60Br24 which have idealized Cs, C2v , and Th symmetries, respectively, have several different types of C-Br and C-C bonds. A comparison between different solvates of the same bromofullerenes revealed a larger stability of the packing modes for the C60Br6 and C60Br24 solvates, whereas the C60Br8 solvates showed different packing motifs dependent on the nature and amount of the solvent molecules. |
