Abstract: The title compound, C₇₀F₃₀·0.5C₆H₆, which crystallizes with one half-molecule of benzene in the asymmetric unit, is one of four isomers of C₆₀(CF₃)₁₀. The benzene molecule is disposed about a center of inversion. The fullerene molecule has an idealized C₆₀-I_h core, with the ten CF₃ groups arranged in an asymmetric para-para-para-meta-para-meta-para-meta-para (p³mpmpmp) ribbon of edge-sharing C₆(CF₃)₂ hexagons. There are no cage Csp³-Csp³ bonds. There are intramolecular FF contacts between pairs of neighboring CF₃ groups, ranging from 2.565 (1) to 2.727 (1) Å.
