Abstract: The absolute structure has been determined by X-ray analysis for the title compound, C₁₁H₈Cl₂O₂. The five-membered ring of the molecule is best described as a flattened envelope conformation with the methylene C atom located 0.208 (2) Å below the plane formed by the other four atoms. A weak intermolecular C-HO hydrogen bond is present in the crystal structure
