In the title compound, C15H11F2N3O2S, the dihedral angle between the fluorobenzene rings is 88.43 (10)° and that between the central semithiocarbazide grouping is 47.00 (11)°. The dihedral angle between the amide group and attached fluorobenzene ring is 50.52 (11)°; the equivalent angle between the carbonylthioamide group and its attached ring is 12.98 (10)°. The major twists in the molecule occur about the C—N—N—C bonds [torsion angle = −138.7 (2)°] and the Car—Car—C—N (ar = aromatic) bonds [−132.0 (2)°]. An intramolecular N—H
O hydrogen bond occurs, which generates an S(6) ring. In the crystal, the molecules are linked by N—HO and N—HS hydrogen bonds, generating (001) sheets. Weak C—HO and C—HF interactions are also observed.
