Abstract
The asymmetric unit of the title compound, C(27)H(32)N(4)O(4)·H(2)O, contains two independent benzimidazole-5-carboxyl-ate mol-ecules and two water mol-ecules. In both main mol-ecules, the pyrrolidine rings are in an envelope conformation with a methyl-ene C atom as the flap. The morpholine rings adopt chair conformations. Both benzimidazole rings are essentially planar, with maximum deviations of 0.008 (1) Å, and form dihedral angles of 37.65 (6) and 45.44 (6)° with the benzene rings. In one mol-ecule, an intra-molecular C-H⋯O hydrogen bond forms an S(7) ring motif. In the crystal, O-H⋯O and O-H⋯N hydrogen bonds connect pairs of main mol-ecules and pairs of water mol-ecules into two independent centrosymmetric four-compoment aggregates. These aggregates are connect by C-H⋯O hydrogen bonds leading to the formation of a three-dimensional network, which is stabilized by C-H⋯π interactions.
