Abstract: In the title compound, C25H29FO4, each cyclohexenone ring has an envelope conformation with the dimethyl-substituted atom as the flap. The hydroxy and carbonyl groups form two intramolecular O-H...O hydrogen bonds, as is typical for xanthene derivatives. In the crystal, very weak C-H...O hydrogen bonds link molecules into dimers.
