Triaqua­(2,2′-bipyridine N,N′-dioxide-κ(2) O,O′)(5-nitro­benzene-1,3-dicarboxyl­ato-κO (1))zinc(II)

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 octa­hedral geometry by three water mol­ecules, one O atom from a 5-nitro­benzene-1,3-dicarboxyl­ate 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 mol­ecules and the carboxyl­ate groups. C—H⋯O inter­actions are also present.
