2-(1H-Benzimidazol-2-yl)phenol.
The title mol-ecule, C13H10N2O, is essentially planar, the maximum deviation from the plane of the non-H atoms being 0.016 (2) Å. The imidazole ring makes a dihedral angle of 0.37 (13)° with the attached benzene ring. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through N-H⋯O hydrogen bonds, forming chains propagating in [001]. The crystal packing also features four π-π stacking inter-actions involving the imidazole ring, fused benzene ring and attached benzene ring system [centroid-centroid distances = 3.6106 (17), 3.6108 (17), 3.6666 (17) and 3.6668 (17) Å].
