Abstract: There are two symmetry-independent molecules, A and B, in the asymmetric unit of the title compound, C15H11FO3S. The crystal studied was an inversion twin with a 0.21 (12):0.79 (12) domain ratio. In the crystal structure, the two independent molecules are related by a pseudo-inversion center. The dihedral angles formed by the phenyl ring and the plane of the benzofuran fragment are 80.2 (1)° in molecule A and 80.7 (1)° in molecule B. In the crystal structure, the A and B molecules are linked by aromatic - interactions between the furan and benzene rings of neighbouring benzofuran systems; the centroid-centroid distances are 3.671 (7) and 3.715 (7) Å. In addition, the crystal structure also exhibits two weak non-classical intermolecular C-HO hydrogen bonds.
