Abstract
In the title compound, [Zn(C22H18N2O4)(H2O)], the Zn-II center, on a crystallographic mirror plane, is in a five-coordinate N2O3 environment that is approximately square pyramidal, with the N2O2 tetradentate Schiff base ligand as the basal plane and the water molecule in the apical position. Intermolecular O-H center dot center dot center dot O and weak C-H center dot center dot center dot O interactions link the molecules into chains along [010]. These chains are further interconnected in a zigzag manner into a threedimensional network.
