In the title compound, C9H7FN4OS, the molecules are almost planar, with an r.m.s. deviation of 0.047 (3) Å from the mean plane defined by the non-H atoms and a maximum deviation of 0.123 (2) Å for the amine N atom. The torsion angle for the N—N—C—S unit is 176.57 (19)°. In the crystal, molecules are linked into inversion dimers via pairs of N—H...F hydrogen bonds and, additionally, through N—H...O and N—H...S hydrogen bonds, building a two-dimensional hydrogen-bond network parallel to the (103) plane. An intramolecular N—H...O interaction is also observed.
