4-(5-Bromo-2-hydroxy­benzyl­idene­amino)-3-methyl-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C(10)H(9)BrN(4)OS, the triazole ring forms a dihedral angle of 72.05 (14)° with the benzene ring. The conformation of the mol­ecule is stabilized by intra­molecular O—H⋯·N hydrogen bonding. The crystal packing is determined by inter­molecular N—H⋯S inter­actions, a short Br⋯S contact of 3.4464 (13) Å and π–π stacking of the triazole rings and of the benzene rings (centroid–centroid distances of 3.4109 and 3.569 Å, respectively).
