In the title molecule, 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 intramolecular O—HN hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked by C—HN and C—HO hydrogen bonds, and consolidated into a three-dimensional architecture by π–π stacking interactions, with a centroid–centroid distance of 3.8428 (12) Å.
