In the title compound, C(29)H(25)N(3)O(3), the imine double bond has an E configuration. The dihedral angle between the hy-droxy-phenyl and benzene rings in the imine moiety is 26.95 (9)°, and the dihedral angle between the hy-droxy-phenyl and benzimidazole rings in the other moiety is 14.83 (9)°. These angles are probably limited to small values as a consequence of two strong intra-molecular O-H⋯N hydrogen bonds formed between the hy-droxy groups and the imine and imidazole N atoms. The aliphatic chain linking the two ring systems has a gauche conformation, as reflected in C-C-C-O torsion angle of 70.9 (2)°.
在标题化合物C(29)H(25)N(3)O(3)中，亚胺双键具有E构型。亚胺部分中羟基苯基与苯环之间的二面角为26.95 (9)°，另一部分中羟基苯基与苯并咪唑环之间的二面角为14.83 (9)°。由于羟基与亚胺和咪唑N原子之间形成了两个强的分子内O-H⋯N氢键，这些角度可能被限制在较小的值。连接两个环系统的脂肪族链具有gauche构象，这反映在C-C-C-O扭转角为70.9 (2)°上。
