RESUMO
In the title compound, C15H11F2N3O2S, the dihedral angle between the fluoro-benzene rings is 88.43â (10)° and that between the central semithiocarbazide grouping is 47.00â (11)°. The dihedral angle between the amide group and attached fluoro-benzene ring is 50.52â (11)°; the equivalent angle between the carbonyl-thio-amide group and its attached ring is 12.98â (10)°. The major twists in the mol-ecule occur about the C-N-N-C bonds [torsion angle = -138.7â (2)°] and the Car-Car-C-N (ar = aromatic) bonds [-132.0â (2)°]. An intra-molecular N-Hâ¯O hydrogen bond occurs, which generates an S(6) ring. In the crystal, the mol-ecules are linked by N-Hâ¯O and N-Hâ¯S hydrogen bonds, generating (001) sheets. Weak C-Hâ¯O and C-Hâ¯F inter-actions are also observed.
