Abstract: In the title compound, C₁₀H₁₁N₃OS, an intramolecular C-HS hydrogen bond is observed, which leads to a thione tautomer in the solid state. The benzene ring forms a dihedral angle of 85.33  (6)° with the triazole ring. There are intermolecular N-HS and O-HN hydrogen bonds and C-H interactions.
