The structure of the title compound C11H7FN2O2S was characterized by single crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P2(1)/n with Z = 12, i.e. with three molecules in asymmetric unit. The molecules are not planar: the dihedral angles between the planes of thiophene and the benzene rings are 42.3(3)A degrees, 42.0(3)A degrees, and 48.9(2)A degrees. In the crystal, intermolecular C-H center dot center dot center dot F interactions link the molecules through R (2) (2) (14) ring motif. The crystal packing is also stabilized by pi center dot center dot center dot pi interactions.
