Intra- and intermolecular C—H...F hydrogen bonds in the crystal structure of 1,2-bis[2-(2,3,4,5-tetrafluorophenyl)ethynyl]benzene
The title mol-ecule, C<sub>22</sub>H<sub>6</sub>F<sub>8</sub>, crystallizes in the monoclinic space group <i>P</i>2<sub>1</sub>/<i>c</i> with two unique mol-ecules in the asymmetric unit and <i>Z</i> = 8. Each mol-ecule features a short intra-molecular <i>sp</i> <sup>2</sup>-C-H⋯F hydrogen bond with H⋯F separations at 2.363 (14) and 2.270 (14) Å, corresponding to 91 and 87.5% of the sum of the van der Waals radii, and C-H⋯F angles of 158.3 (14) and 166.8 (14)°, respectively. Each mol-ecule also forms an inter-molecular bifurcated CH⋯(F)<sub>2</sub> inter-action with H⋯F distances ranging from 2.500 (16) to 2.597 (17) Å.
