The title molecule, C15H21N3S, exists as the thione tautomer in the solid state. The 1,2,4-triazole ring is almost planar (r.m.s. deviation = 0.004 Å) and the prop-2-en-1-yl chain is close to being perpendicular to this plane [C—N—C—C torsion angle = 77.1 (5)°]. In the crystal, centrosymmetric dimeric aggregates are formed by pairs of N—HS hydrogen bonds as parts of eight-membered (HNCS)2 synthons. These are connected into layers parallel to (101) via C—Hπ interactions, where the π-system is the triazole ring. The investigated sample was a nonmerohedral twin; the refined domain ratio was 0.655 (4):0.345 (4).

In the title molecule, C17H21FN2S, the mean planes of the benzene ring and the thiourea fragment form a dihedral angle of 61.93 (9)°. In the crystal, pairs of weak N—HS interactions link the molecules, forming inversion dimers.
