In the title compound, C(26)H(25)FO(5), the terminal cyclo­hexane rings of the xanthene ring system adopt half-boat conformations. The 4H-chromene ring make a dihedral angle of 87.94 (5)° with the xanthene ring system and its carbonyl O atom lies above the xanthene O atom. In the crystal, mol­ecules...

description In the title compound, C(26)H(25)FO(5), the terminal cyclo­hexane rings of the xanthene ring system adopt half-boat conformations. The 4H-chromene ring make a dihedral angle of 87.94 (5)° with the xanthene ring system and its carbonyl O atom lies above the xanthene O atom. In the crystal, mol­ecules are linked into ribbons propagating along the a-axis direction by C—H⋯O hydrogen bonds. Aromatic π–π stacking inter­actions [centroid–centroid distance = 3.7367 (12) Å] also occur.
