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.
在标题分子C(15)H(14)N(2)O(2)中，取代苯环与苯并咪唑环系形成4.15 (1)°的二面角。分子内O-H⋯N氢键生成一个S(6)环模式。在固态中，分子通过分子间分叉的N-H⋯(O,O)氢键沿[001]方向连接成链，这些氢键生成R(1) (2)(5)环模式。晶体堆积还通过C-H⋯π相互作用以及咪唑环与取代苯环之间的π-π堆积相互作用得到巩固[质心-质心距离 = 3.5746 (13) Å]。连接在苯并咪唑环系上的甲基在两个位置上无序，占有率分别为0.587 (6)和0.413 (6)，表明苯并咪唑基团存在180°旋转无序。
