RESUMO
The title compound, C16H9FN2S, crystallizes as a nonmerohedral twin with twin rotation about the reciprocal-lattice vector [101]*. The molecules are nearly planar and the dihedral angle between the planes of the two aryl rings is only 4.4â (2)°. The molecules are linked by pairs of C-H···N hydrogen bonds to form cyclic centrosymmetric R2(2)(18) dimers, which are linked into chains by an aromatic π-π stacking interaction. Comparisons are made with some related 3-aryl-2-thienylacrylonitriles.
