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.
标题化合物C29H24FNO5·0.5CH3OH的不对称单元包含两个独立分子和一个甲醇溶剂分子。甲醇分子通过O—H⋯O氢键与其中一个独立分子相连。两个分子中的吡咯烷环均呈半椅式构象，而茚满基团内的环戊烷环呈扁平信封式构象，螺碳原子形成折边。茚满环系的苯环在一个独立分子中形成的二面角为35.06 (7)°，在另一个独立分子中为31.16 (8)°。氟取代苯环在一个分子中与茚满基团苯环形成的二面角为65.35 (6)°和85.87 (7)°，在另一个分子中为72.78 (8)°和77.27 (8)°。在每个分子中，一个弱的分子内C—H⋯O氢键形成一个S(6)环模式。在晶体中，弱的C—H⋯O、C—H⋯N和C—H⋯F氢键将分子连接成三维网络。
