Abstract
In the title compound, C(6)H(3)F(3), weak electrostatic and dispersive forces between C(δ+)-F(δ-) and H(δ+)-C(δ-) groups are at the borderline of the hydrogen-bond phenomenon and are poorly directional and further deformed in the presence of π-π stacking inter-actions. The mol-ecule lies on a twofold rotation axis. In the crystal structure, one-dimensional tapes are formed via two anti-dromic C-H⋯F hydrogen bonds. These tapes are, in turn, connected into corrugated two-dimensional sheets by bifurcated C-H⋯F hydrogen bonds. Packing in the third dimension is furnished by π-π stacking inter-actions with a centroid-centroid distance of 3.6362 (14) Å.
