Abstract

In the title compound, C12H8F2N2OS, the thienyl ring is disordered over two positions, with the S atom of the major component [occupancy = 75.03 (18)%] oriented away from an ortho-F atom of the benzene ring. The mol­ecule is nearly planar, the dihedral angle between the thio­phene and benzene rings being 6.19 (18) (in the major component) or 3.5 (6)° (in the minor component). The azomethine C=N double-bond in the mol­ecule is of an E configuration. In the crystal, mol­ecules are linked by pairs of N—H⋯O hydrogen bonds, generating inversion dimers.
