In the title compound, C 27H 20ClNO 3, the two cyclopentane rings adopt envelope conformations. The pyrrolidine ring also adopts an envelope conformation (with the spiro C atom as the flap) and its leastsquares plane (fitted to five atoms) makes dihedral angles of 66.50 (9), 77.36 (8) and 73.76 (8)° with the chlorobenzene ring and the two 2,3-dihydro-1H-indene ring systems, respectively. The molecular conformation is stabilized by an intramolecular C - H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked by C - H⋯O hydrogen bonds into chains running parallel to the  direction.
