Haloaryl Carboranes. I. 1,4-Bis[2-phenyl-1,2-dicarba-closo-dodecaboran(12)-1-yl]-2,3,5,6-tetrafluorobenzene

The title molecule, C₂₂H₃₀B₂₀F₄, has a crystallographically imposed inversion centre. The twist angle (θ) of the phenyl ring is 15.6 (3)°, and that of the haloaryl ring is 3.7 (3)°, these low values are presumably a consequence of the mutual steric crowding of the rings. The C_cage-C_cage distance is 1.730 (3) Å, in good agreement with that found in similar molecules.
