ABSTRACT
The solubility of C60F18 in aromatic hydrocarbons, benzene, toluene, and xylenes (0.48–1.23 mg/mL), and decomposition enthalpies for the 1 : 1 and 1 : 2 complexes (31–70 kJ/mole) have been determined. The C60F18 molecule has near perfect C3v symmetry, and the x-ray single-crystal structures of the C60F18 L complexes (L=hexamethylbenzene, o-, m-, p-xylene, and bromobenzene) are compared in terms of 12 types of C‒C and four types of C–F bonds. Analysis of the packing modes in the crystals shows an influence of the size and polarity of the aromatic hydrocarbon molecule.
