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) degrees with that of the triazole group. In the crystal, molecules are linked by O-H center dot center dot center dot 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 center dot center dot center dot N hydrogen-bond interactions. Aromatic pi- pi stacking [centroid-centroid separation = 3.556 (1) angstrom] between the triazole rings links the layers into a three-dimensional network.
