✦ Synopsis

The Zn atom in the title compound, [Zn(C 11 H 13 N 2 O 6 ) 2 ]Á3H 2 O, is chelated by the two terdentate Schiff base anions, resulting in a trans-ZnN 2 O 4 octahedral geometry. The crystal packing is stabilized by O-HÁ Á ÁO hydrogen bonds, leading to a threedimensional network structure.
