(E)-2-(1,3-Benzothiazol-2-yl)-3-(4-fluorophenyl)acrylonitrile: a chain of π-stacked hydrogen-bonded rings

Abstract

The title compound, C16H9FN2S, crystallizes as a nonmerohedral twin with twin rotation about the reciprocal-lattice vector [10\overline{1}]*. The molecules are nearly planar and the dihedral angle between the planes of the two aryl rings is only 4.4 (2)°. The molecules are linked by pairs of C—H...N hydrogen bonds to form cyclic centrosymmetricR22(18) dimers, which are linked into chains by an aromatic π–π stacking interaction. Comparisons are made with some related 3-aryl-2-thienylacrylonitriles.
