In the title mol-ecule, C(22)H(20)N(2)O(4), the dihedral angles between the benzimidazole ring system and the benzene rings are 44.26 (2) and 82.91 (2)°. Intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, O-H⋯N and O-H⋯O hydrogen bonds connect the mol-ecules into a two-dimension network parallel to (10[Formula: see text]) and weak inter-molecular C-H⋯O hydrogen bonds complete the formation of a three-dimensional network.
在标题分子C₂₂H₂₀N₂O₄中，苯并咪唑环系与苯环之间的二面角分别为44.26 (2)°和82.91 (2)°。分子内存在O—H⋯O氢键。在晶体中，O—H⋯N和O—H⋯O氢键将分子连接成平行于(10[化学式：见原文])的二维网络，且弱的分子间C—H⋯O氢键完成了三维网络的形成。
