Abstract

In the title compound, (C4H8N3O)2[Zn(C7H3NO4)2(H2O)2]·2H2O, the ZnII ion is six-coordinated in a distorted octa­hedral geometry by two pyridine-2,4-dicarboxyl­ate (pydc) ligands in the equatorial plane and two water mol­ecules in the axial positions. The pydc ligands act as bidentate chelating ligands through one carboxyl­ate O atom and the pyridine N atom. Inter­molecular N—H⋯O, O—H⋯O and weak C—H⋯O hydrogen bonds stabilize the crystal structure.
