The racemic title compound, C30H26Cl3N3O2, comprises two spiro links, the first connecting the piperidine and pyrrolidine rings and the other connecting the indole and pyrrolidine rings. The piperidine ring adopts a half-chair conformation, while the pyrrolidine ring has an envelope conformation with the unsubstituted C atom as the flap. The dihedral angles between the two p-Cl-substituted benzene rings and the indole ring are 33.13 (14) and 54.11 (14)°. In the crystal, mol­ecules form inversion dimers through pairs of N—H...O hydrogen bonds [graph set R22(8)]. Aromatic C—H...O hydrogen bonds extend these dimers into a ribbon structure, enclosing R22(14) ring motifs, along the a-axis direction.
