(Z)-2-Acetamido-3-(4-chloro­phen­yl)acrylic acid

In the title compound, C11H10ClNO3, the mol­ecule consists of a benzene ring and an acetamido­acrylic acid unit on opposite sides of the C=C double bond. In the crystal, inter­molecular O—H⋯O and N—H⋯O hydrogen bonds assemble the mol­ecules into infinite two-dimensional ribbons. These ribbons are linked into a network by inter­molecular C—H⋯π contacts.
