2-(1H-Benzimidazol-2-yl)phenol

The title mol­ecule, C(13)H(10)N(2)O, 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 intra­molecular O—H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are linked through N—H⋯O hydrogen bonds, forming chains propagating in [001]. The crystal packing also features four π–π stacking inter­actions 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].
