In the title compound, [Zn(C(8)H(3)NO(6))(C(10)H(8)N(2)O(2))(H(2)O)(3)], the Zn(II) ion is coordinated in a distorted octa-hedral geometry by three water mol-ecules, one O atom from a 5-nitro-benzene-1,3-dicarboxyl-ate ligand and two O atoms from a chelating 2,2'-bipyridine N,N'-dioxide ligand. An extensive network of O-H⋯O hydrogen bonds is formed between the water mol-ecules and the carboxyl-ate groups. C-H⋯O inter-actions are also present.
