2-[1-(2-Hydroxy-3-methoxybenzyl)-1H-benzimidazol-2-yl]-6-methoxyphenol monohydrate

The asymmetric unit of the title compound, C(22)H(20)N(2)O(4)·H(2)O, comprises a substituted benzimidazole molecule and a water mol­ecule of crystallization. The dihedral angles between the benzimidazole ring system and the two outer benzene rings are 16.54 (4) and 86.13 (4)°. The dihedral angle between the two hydr­oxy-substituted benzene rings is 82.20 (5)°. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds, involving the hydr­oxy groups and water mol­ecules, form R (4) (4)(8) ring motifs, and link symmetry-related mol­ecules into extended chains along the c axis. The crystal structure is further stabilized by weak inter­molecular C—H⋯O hydrogen bonds, weak C—H⋯π and π–π stacking [centroid–centroid = 3.6495 (6)–3.7130 (6) Å] inter­actions. Intra­molecular O—H⋯O and O—H⋯N inter­actions are also present.
