2-(1-Phenyl-1H-benzimidazol-2-yl)phenol.

In the title mol-ecule, C19H14N2O, the benzimidazole unit is close to being planar [maximum deviation = 0.0253 (11) Å] and forms dihedral angles of 68.98 (6) and 20.38 (7)° with the adjacent phenyl and benzene rings; the dihedral angle between the latter two planes is 64.30 (7)°. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯N and C-H⋯O hydrogen bonds, and consolidated into a three-dimensional architecture by π-π stacking inter-actions, with a centroid-centroid distance of 3.8428 (12) Å.
