Abstract

In the title mol-ecule, C(15)H(14)N(2)O(2), the substituted benzene ring forms a dihedral angle of 4.15 (1)° with the benzimidazole ring system. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the solid state, mol-ecules are linked into chains along the [001] via inter-molecular bifurcated N-H⋯(O,O) hydrogen bonds, which generate R(1) (2)(5) ring motifs. The crystal packing is also consolidated by C-H⋯π inter-actions, and π-π stacking inter-actions between the imidazole and substituted benzene rings [centroid-centroid distance = 3.5746 (13) Å]. The methyl group attached to the benzimidazole ring system is disordered over two positions with occupancies of 0.587 (6) and 0.413 (6), suggesting 180° rotational disorder for the benzimidazole group.
