Abstract: In the title compound, C13H9N3O2·C3H7NO, the benzimidazole ring system and the benzene ring are essentially coplanar, forming a dihedral angle of 0.86 (5)°. The crystal packing is stabilized by an intermolecular N-HO hydrogen bond and a - stacking interaction with a centroid-centroid separation of 3.685 (4) Å.
