Abstract: The title molecule, C12H12FN3O2S, shows a short intramolecular S...O contact of 2.682 (18) Å. The dihedral angle between the thiadiazole ring and the benzene ring is 86.82 (11)°. In the crystal, N-H...O and C-H...O hydrogen bonds generate an R21(6) graph-set motif between adjacent molecules. Pairs of futher C-H...O hydrogen bonds form inversion dimers with R22(8) ring motifs. These combine to generate a three-dimensional network and stack the molecules along the b axis.
