In the title compound, C13H9Cl2NO, the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-Cl atom in the aniline ring is positioned syn to the N—H bond. The two aromatic rings are almost coplanar, making a dihedral angle of 4.73 (5)°. The crystal structure is stabilized by N—HO hydrogen bonds, which link the molecules into chains along the b axis.

The asymmetric unit of the title polymeric mononuclear CuII complex, [Cu(C2N3)2(NH3)2]n, contains one half-molecule, the complex being completed through inversion symmetry, with the CuII atom situated on the centre of symmetry. The coordination polyhedron around CuII is a Jahn–Teller-distorted [CuN6] octahedron. The terminal N atoms of two dicyanamide ligands and two ammine ligands form an approximate square plane, with N—Cu—N bite angles of 89.72 (5) and 90.28 (5)°. The coordination polyhedron is completed in the axial positions by the central amide-type N atoms of two additional dicyanamide ligands, with an elongated Cu—N distance of 2.548 (1) Å. In turn, each of the four dicyanamide ligands, acting as bidentate, link the CuII ions into a two-dimensional polymeric structure parallel to (100). The ammine H atoms are involved in intermolecular hydrogen bonding with the free terminal N atoms of neighbouring dicyanamide ligands, yielding a three-dimensional network.

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.
