Abstract: The molecule of the title compound, C₁₁H₆ClO₃P, is essentially planar, except for the P, Cl and carbonyl O atoms. Bond lengths at phosphorus are P-O = 1.6110  (18) and 1.6290  (18)  Å, and P-Cl = 2.0890  (9)  Å. The molecules are linked to form ribbons parallel to the b axis by two C-HO and one PO interaction.
