Abstract: The title compound, C10H7ClN2O5·H2O, crystallizes with a half-molecule each of N-(2-chloro-4-nitrophenyl)maleamic acid (located on a mirror plane) and water (located on a twofold rotation axis) in the asymmetric unit. The main molecule is planar by symmetry and its conformation is stabilized by an intramolecular O-HO hydrogen bond. In the crystal, N-HO and O-HO hydrogen bonds link the molecules into a three-dimensional network.
