چکیده
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.
