Abstract
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—H⋯O hydrogen bonds, forming dimers with R 2 2(6) ring motifs, and by O—H⋯Cl hydrogen bonds. There are short Cl⋯Cl [3.4728 (16), 3.4863 (16), and 3.388 (1) Å] contacts present, and molecules are also linked by C—H⋯O and π–π [centroid–centroid distance = 3.671 (2) Å] interactions.

The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
