In the title compound, [Zn(C(4)H(4)N(3)O(2))(2)](n), the Zn(II) atom is coordinated by two O atoms [Zn-O = 1.969 (2) and 1.997 (2) Å] and two N atoms [Zn-N = 2.046 (2) and 2.001 (2) Å] in a distorted tetra-hedral geometry. Non-classical inter-molecular C-H⋯O hydrogen bonds link the complex into a three-dimensional supra-molecular framework.
