Triaqua­(2,2′-bipyridine-κ(2) N,N′)(5-nitro­isophthalato-κO (1))zinc(II) monohydrate

In the title compound, [Zn(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)(3)]·H(2)O, the Zn(II) cation is hexa­coordinated by a chelating 2,2′-bipyridine ligand, one carboxyl­ate O atom from a 5-nitro­isophthalate dianion and three water mol­ecules in a slightly distorted octa­hedral geometry. The structure contains isolated neutral complexes, in contrast to coordination polymers formed by Mn(II), Co(II) and Cu(II) with the same ligand set. An extensive network of hydrogen bonds is formed between the water mol­ecules and the carboxyl­ate groups.
