Deskripsi
The weak electrostatic and dispersive forces between C(δ+)—F(δ−) and H(δ+)—C(δ−) are at the borderline of the hydrogen-bond phenomenon and are poorly directional and further deformed in the presence of other dominant interactions, e.g. C—H...π. The title compound, C6H4F2, Z′ = 2, forms one-dimensional tapes along two homodromic C—H...F hydrogen bonds. The one-dimensional tapes are connected into corrugated two-dimensional sheets by further bi- or trifrucated C—H...F hydrogen bonds. Packing in the third dimension is controlled by C—H...π interactions.
