In the title compound, C19H18Cl4N2O2, a potential tetradentate Schiff base ligand, the dihedral angle between the two benzene rings is 48.01 (10)°. The configuration about the two C=N bonds is E and two intramolecular O—H
N hydrogen bonds make S(6) ring motifs. In the crystal, molecules are linked along the b axis via intermolecular C—HCl interactions. The crystal structure is further stabilized by an intermolecular π–π interaction [centroid–centroid distance = 3.5744 (12) Å].

In the title Schiff base complex, [Cu(C19H16Cl4N2O2)], the geometry around the CuII atom is distorted square-planar defined by the N2O2 donor atoms of the coordinated ligand. The dihedral angle between the substituted benzene rings is 29.95 (16)°. In the crystal, molecules are linked along the b axis, forming individual dimers through C—HO interactions. The crystal structure is further stabilized by intermolecular π–π interactions [centroid–centroid distance = 3.6131 (17) Å].

In the title compound, [Ni(C19H16Cl4N2O2)], the NiII ion is in a distorted square-planar environment coordinated by two N atoms and two O atoms of the tetradentate ligand. The dihedral angle between the benzene rings is 24.8 (2)°. In the crystal, molecules are linked into chains along the b axis by weak C—HO and C—HCl interactions. An intermolecular ClCl [3.4564 (19) Å] interaction is present which is shorter than the sum of the van der Waals radii of Cl atoms (3.50 Å).

The asymmetric unit of the title compound, [Zn(C19H16Cl4N2O2)(H2O)], comprises two crystallographically independent molecules. The geometry around the ZnII atoms is distorted trigonal–bipyramidal, supported by the N2O2 donor atoms of the tetradentate Schiff base and a coordinating water molecule. The dihedral angles between the benzene rings in the two molecules are 34.10 (15) Å and 30.61 (15) Å. In the crystal, neighbouring independent molecules are linked by pairs of O—HO hydrogen bonds, forming dimers with R22(6) ring motifs, and by O—HCl hydrogen bonds. There are short ClCl [3.4728 (16), 3.4863 (16), and 3.388 (1) Å] contacts present, and molecules are also linked by C—HO and π–π [centroid–centroid distance = 3.671 (2) Å] interactions.
