5-[(E)-2-Fluoro­benzyl­idene]-8-(2-fluoro­phen­yl)-2-hy­droxy-10-methyl-3,10-di­aza­hexa­cyclo­[10.7.1.1(3,7).0(2,11).0(7,11).0(16,20)]henicosa-1(20),12,14,16,18-pentaen-6-one

In the title compound, C(33)H(26)F(2)N(2)O(2), the piperidone ring adopts a half-chair conformation and the pyrrolidine rings adopt half-chair and envelope conformations. The two benzene rings make dihedral angles of 29.58 (5) and 76.33 (5)° with the mean plane of the 1,2-dihydro­acenaphthyl­ene unit. An intra­molecular O—H⋯N hydrogen bond helps to stabilize the mol­ecular structure. In the crystal, inter­molecular C—H⋯F hydrogen bonds link the mol­ecules into [010] chains. Weak C—H⋯π inter­actions are also observed.
