Deskripsi
In the title compound, C27H20ClNO3, 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 least-squares 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 [001] direction.
