Abstract: The molecular structure of the title compound, C₁₀H₈Cl₂O₃, exists in a cis-enol form, which is stabilized by a strong intramolecular O-HO hydrogen bond. In the crystal, C-HO interactions generate zigzag chains along the c axis which are, in turn, linked by further C-HO interactions into sheets parallel to (100).
