(Z)-Methyl 3-(2,4-dichlorophenyl)-3-hydroxyacrylate

Abstract

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