4-[(E)-(4-Hydroxybenzylidene)amino]-3-methyl-1H-1,2,4-triazole-5(4H)-thione

The title compound, C10H10N4OS, is nearly planar with the mean planes of the hydroxybenzyl and triazole rings inclined at an angle of only 3.2 (7)°. In the crystal, O—H...N hydrogen bonds between the hydroxy group and the triazole ring in concert with weak N—H...S intermolecular interactions between the triazole ring and thione group form chains along [-210] enclosing R22(8) graph-set motifs. A weak intramolecular C—H...S interaction and intermolecular π–π interactions [centroid–centroid distance = 3.5990 (15) Å] are also observed
