Crystal structure of 4-{[(1H-1,2,4-triazol-1-yl)meth­yl]sulfan­yl}phenol

In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40 (5)° with that of the triazole group. In the crystal, mol­ecules are linked by O—H⋯N hydrogen bonds involving the phenol –OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C—H⋯N hydrogen-bond inter­actions. Aromatic π–π stacking [centroid–centroid separation = 3.556 (1) A] between the triazole rings links the layers into a three-dimensional network.
