Abstract
In the title compound, C38H28F2N2O2, the piperidine ring adopts a chair conformation and the pyrrolidine ring adopts an envelope conformation with the spiro C atom as the flap atom. The naphthalene ring system makes dihedral angles of 39.89 (8), 35.33 (8) and 46.45 (8)° with the two fluoro-substituted benzene rings and the phenyl ring, respectively, while the dihedral angle between the two fluoro-substituted benzene rings is 75.21 (10)°. An intramolecular O—H⋯N hydrogen bond generates an S(5) ring. In the crystal, molecules are connected by C—H⋯O hydrogen bonds, forming supramolecular chains propagating along the c-axis direction. Weak C—H⋯π interactions further consolidate the structure.

Cg5, Cg6, Cg7 and Cg9 are the centroids of the C1–C5/C10, C5–C10, C22–C27 and C34–C39 rings, respectively
The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry
