4-Amino-3-(4-hydroxybenzyl)-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C9H10N4OS, the dihedral angle between the benzene and 1H-1,2,4-triazole-5(4H)-thione rings is 67.51(16)°. In the crystal, molecules are liked via N-H.O hydrogen bonds, forming chains along the c-axis direction. The chains are linked via O-H.S hydrogen bonds, forming corrugated layers lying parallel to the bc plane. The layers are linked via N-H.N and N-H.S hydrogen bonds, forming a three-dimensional network
