Bottom Line: An intra-molecular C-H⋯O hydrogen bond forms an S(8) ring motif.The mean plane through the pyrrolidine ring [r.m.s. deviation = 0.179 (2) Å] makes dihedral angles of 86.30 (13), 88.99 (10) and 79.69 (11)° with the benzene ring, the dihydro-acenaphthyl-ene ring and the mean plane of the indane system, respectively.In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N hydrogen bonds into a two-dimensional network parallel to the ac plane.

ABSTRACT
In the title compound, C(31)H(22)F(3)NO(2), the pyrrolidine and cyclo-pentane rings within the dihydro-indene ring system are in envelope conformations, with the N atom and the spiro-C atom at the flap, respectively. An intra-molecular C-H⋯O hydrogen bond forms an S(8) ring motif. The mean plane through the pyrrolidine ring [r.m.s. deviation = 0.179 (2) Å] makes dihedral angles of 86.30 (13), 88.99 (10) and 79.69 (11)° with the benzene ring, the dihydro-acenaphthyl-ene ring and the mean plane of the indane system, respectively. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N hydrogen bonds into a two-dimensional network parallel to the ac plane. C-H⋯π inter-actions further stabilize the crystal structure.
