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 R22(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 [pi]-[pi] [centroid-centroid distance = 3.671 (2) Å] interactions.
