Abstract
The asymmetric unit of the title compound, C29H24FNO5·0.5CH3OH, contains two independent mol-ecules and a one methanol solvent mol-ecule. The methanol mol-ecule is O-H⋯O hydrogen bonded to one of the independent mol-ecules. The pyrrolidine rings in both mol-ecules adopt half-chair conformations, while the cyclo-pentane 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 mol-ecule 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 mol-ecule, and 72.78 (8) and 77.27 (8)° in the other. In each mol-ecule, a weak intra-molecular C-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, weak C-H⋯O, C-H⋯N and C-H⋯F hydrogen bonds link the mol-ecules into a three-dimensional network.
