Abstract: The furan ring and the five-membered fluorene unit in the title compound, C₂₆H₂₂Cl₂O₄, adopt envelope conformations. Intermolecular C-HO interactions between symmetry-related molecules involving two C-H groups and an O atom as a bifurcated acceptor generate centrosymmetric hydrogen-bonded dimers with cyclic R₂²(16) and R₂²(8) ring motifs. A short C-HCl intramolecular contact occurs in the molecule.
