Abstract: The title Schiff base compound, C₁₅H₁₄N₂O₂, consists of two crystallographically independent molecules, A and B. Molecule A is almost planar, whereas molecule B is slightly twisted, the dihedral angles between the benzimidazole group and the benzene rings being 2.65 (12) and 13.17 (15)°, respectively. The methyl group of molecule B is disordered over two positions, with a refined site-occupancy ratio of 0.581 (7):0.419 (7). In each molecule, intramolecular O-HN hydrogen bonds generate S(6) ring motifs. In the crystal structure, both types of molecules are linked via intermolecular bifurcated N-HO hydrogen bonds into one-dimensional extended chains along [010] and form R₁²(5) ring motifs. The crystal structure is further stabilized by intermolecular C-H and - interactions [centroid-centroid distances = 3.4758 (16)-3.596 (2) Å].
