The asymmetric unit of the title compound, C29H24FNO5·0.5CH3OH, contains two independent molecules and a one methanol solvent molecule. The methanol molecule is O-HO hydrogen bonded to one of the independent molecules. The pyrrolidine rings in both molecules adopt half-chair conformations, while the cyclopentane rings within the indane groups are in flattened envelope conformations, with the spiro C atoms forming the flaps. The benzene rings of the indane ring systems form a dihedral angle of 35.06 (7)° in one independent molecule and 31.16 (8)° in the other. The fluoro-substituted benzene ring forms dihedral angles of 65.35 (6) and 85.87 (7)° with the indane group benzene rings in one molecule, and 72.78 (8) and 77.27 (8)° in the other. In each molecule, a weak intramolecular C-HO hydrogen bond forms an S(6) ring motif. In the crystal, weak C-HO, C-HN and C-HF hydrogen bonds link the molecules into a three-dimensional network.
