The mol-ecular structure is stabilized by two intra-molecular hydrogen bonds. The first is a short O-H⋯O hydrogen bond (H⋯O distance = 1.57 Å) within the maleamic acid unit and the second is a C-H⋯O hydrogen bond (H⋯O distance = 2.24 Å) which connects the amide group with the benzene ring. The nitro group is twisted by 6.2 (2)° out of the plane of the benzene ring. The crystal structure manifests a variety of hydrogen bonding. The packing is dominated by a strong inter-molecular N-H⋯O inter-action which links the mol-ecules into chains running along the b axis. The chains within a plane are further assembled by three additional types of inter-molecular C-H⋯O hydrogen bonds to form a sheet parallel to the (01) plane.Acta crystallographica.
