Abstract
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 angstrom for the non-H atoms. The dihedral angle between the two chloro-substituted benzene rings is 63.69 (10)degrees. Intramolecular CH center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds may influence the molecular conformation. In the crystal structure, molecules are connected into layers by weak intermolecular C-H center dot center dot center dot O hydrogen bonds.
