N-(3-Chloro-4-methylphenyl)maleamic acid

Abstract

In the title compound, C11H10ClNO3, the dihedral angle between the benzene ring and the amide group is 6.6 (10)° and an intramolecular O—H⋯O hydrogen bond occurs. In the crystal, molecules are linked by N—H⋯O hydrogen bonds, generating C(7) zigzag chains.
