Figure 2 (Left) Schlegel diagram showing the IUPAC lowest-locants for the cage carbon atoms. The C2 axis passes through the center of the hexa­gon with C19 and C41 and bis­ects the C30—C50 bond. The CF3 groups are attached to the cage carbon atoms depicted as black circles. Also shown is the ribbon of meta- and para-C6(CF3)2 edge-sharing hexa­gons (the two meta-C6(CF3)2 hexa­gons are indicated with the letter m). (Right) The structure showing the atom numbers for the CF3 groups and the network of F⋯F contacts between CF3 groups that share the same hexa­gon.
