Abstract
In the title compound, C31H22F3NO2, the pyrrolidine and cyclopentane rings within the dihydroindene ring system are in envelope conformations, with the N atom and the spiro-C atom at the flap, respectively. An intramolecular 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 dihydroacenaphthylene ring and the mean plane of the indane system, respectively. In the crystal, molecules 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 interactions further stabilize the crystal structure.
