Figure 2 . Part of the crystal structure of (I) showing the zigzag chains generated by N—H⋯O hydrogen bonds and extending parallel to the c axis. The chains are weakly coupled by π-π inter­action between the phenyl rings and maleamic acid groups. The dashed lines depict the hydrogen bonds, the dotted line depicts the short contact Cg⋯C4ii. H atoms not involved in hydrogen bonding have been omitted. [Symmetry codes (i): x, −y + [{3\over 2}], z − [{1\over 2}]; (ii) −x,-y + 1,-z + 1].
