In the title compound, C20H22N2O3·0.25H2O, the water molecule (occupancy 0.25) is disordered across a crystallographic inversion center. The dihedral angle between the hydroxyphenyl ring and the benzimidazole ring system is 59.31 (9)°. In the crystal structure, molecules are connected by intermolecular O—HN and C—HO hydrogen bonds. The crystal structure is further stabilized by a weak C—Hπ interaction involving the imidazole ring.

In the title compound, C32H26Cl2N2O3, the piperidone ring adopts a chair conformation and the proline and pyrrolidine rings adopt envelope conformations. The indane ring system is essentially planar with an r.m.s. deviation of 0.011 Å for the non-H atoms. The dihedral angle between the two chloro-substituted benzene rings is 63.69 (10)°. Intramolecular C—HO and N—HO hydrogen bonds may influence the molecular conformation. In the crystal structure, molecules are connected into layers by weak intermolecular C—HO hydrogen bonds.
