In the title compound, (C(4)H(8)N(3)O)(2)[Zn(C(7)H(3)NO(4))(2)(H(2)O)(2)]·2H(2)O, the Zn(II) ion is six-coordinated in a distorted octa-hedral geometry by two pyridine-2,4-dicarboxyl-ate (pydc) ligands in the equatorial plane and two water mol-ecules in the axial positions. The pydc ligands act as bidentate chelating ligands through one carboxyl-ate O atom and the pyridine N atom. Inter-molecular N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds stabilize the crystal structure.
在标题化合物（C₄H₈N₃O）₂[Zn（C₇H₃NO₄）₂（H₂O）₂]·2H₂O中，Zn（II）离子通过赤道平面上的两个吡啶-2,4-二羧酸酯（pydc）配体和轴向位置的两个水分子以扭曲的八面体几何构型进行六配位。pydc配体通过一个羧酸根O原子和吡啶N原子作为双齿螯合配体。分子间的N-H⋯O、O-H⋯O和弱C-H⋯O氢键稳定了晶体结构。
