1,4,10,14,19,25,35,41,49,60,66,69-dodecakis(trifluoromethyl)-1,4,10,14,19,25,35,41,49,60,66,69-dodecahydro(C70-D5h(6))[5,6]fullerene benzene disolvate

The title compound, which crystallized with two molecules of benzene in the asymmetric unit, C(82)F(36)(.)2C(6)H(6), is one of two isomers of C-70(CF3)(12) that represent the first structurally characterized fullerene derivatives with exactly 12 substituents. This isomer consists of an idealized D-5h-C-70 core with the 12 CF3 groups arranged on a para(7)-meta-para ribbon of edge-sharing C-6(CF3)(2) hexagons plus an isolated C-6(CF3)(2) hexagon. There are no cage Csp(3)-Csp(3) bonds. As in the recently published structures of C-s-C-70(CF3)(8) and C-1-C-70(CF3)(10), there are numerous F (.) (.) (.) F intramolecular contacts between pairs of neighboring CF3 groups that range from 2.526 (5) to 2.930 (5) angstrom.
