Abstract
In the title complex, [Zn(C20H14N2O4)(H2O)] center dot 3H(2)O, the Zn-II center is in an approximately square-pyramidal coordination environment with the two N and two O atoms of the tetradentate Schiff base ligand forming the basal plane and the coordinated water molecule in the apical position. Three solvent water molecules complete the asymmetric unit. The dihedral angles between the two outer benzene rings of the Schiff base and the central benzene ring are 12.64 (14) and 17.25 (14)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O hydrogen bonds link the molecules into sheets parallel to the ab plane.
