The title compound, 0.75C(15)H(14)N(2)O.0.25C(15)H(14)N(2)O, is a co-crystal of 2-methyl-6-(6-methyl-1H-benzimidazol-2-yl)phenol as the major component and 2-methyl-6-(5-methyl-1H-benz-imidazol-2-yl)phenol as the minor component. The refined site-occupancy ratio is 0.746 (4)/0.254 (4). The conformations of both components are identical except for that of the methyl substituent on the benzene ring of the benzimidazole unit which is positionally disordered over two positions. The mol-ecule is essentially planar, the dihedral angle between the benzimidazole plane and the benzene ring being 3.49 (4) degrees . An intra-molecular O-Hcdots, three dots, centeredN hydrogen bond generates an S(6) ring motif. In the crystal packing, mol-ecules are linked through N-Hcdots, three dots, centeredO hydrogen bonds into chains along [201]. These chains are stacked approximately along the a-axis direction. The crystal packing is further stabilized by weak N-Hcdots, three dots, centeredO and Ocdots, three dots, centeredHcdots, three dots, centeredN hydrogen bonds, together with weak inter-molecular C-Hcdots, three dots, centeredpi inter-actions. A pi-pi inter-action with a centroid-centroid distance of 3.6241 (6) A is also observed between the substituted phenyl ring and that of the benzimidazole system.
