The absolute structure has been determined by X-ray analysis for the title compound, C(11)H(8)Cl(2)O(2). The five-membered ring of the mol-ecule is best described as a flattened envelope conformation with the methyl-ene C atom located 0.208 (2) Å below the plane formed by the other four atoms. A weak intermolecular C-H⋯O hydrogen bond is present in the crystal structure.
