Intra- and inter-molecular C-H⋯F hydrogen bonds in the crystal structure of 1,2-bis-[2-(2,3,4,5-tetra-fluoro-phen-yl)ethyn-yl]benzene

The title mol-ecule, C(22)H(6)F(8), crystallizes in the monoclinic space group P2(1)/c with two unique mol-ecules in the asymmetric unit and Z = 8. Each mol-ecule features a short intra-molecular sp (2)-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)(2) inter-action with H⋯F distances ranging from 2.500 (16) to 2.597 (17) Å.
