In the title mononuclear ZnII complex, [Zn(C13H19N2O2)2]·2H2O, the ZnII atom is coordinated by two O atoms and three N atoms from two crystallographically different Schiff base ligands in a distorted trigonal–bipyramidal environment. One O and two N atoms constitute the base of the pyramid, and one O and one N atoms occupy the apical positions. Intermolecular O—H...O and O—H...N hydrogen bonds between the lattice water molecules and N/O atoms of the Schiff base ligands stabilize the conformation, whereas intermolecular O—H...O hydrogen bonds between the two lattice water molecules lead to a chain structure in [001].
