title: Poly[[mu2-4,4'-bipyridine-di-mu3-sulfito-dizinc(II)] monohydrate].
abstract: The title compound, {[Zn(2)(SO(3))(2)(C(10)H(8)N(2))].H(2)O}(n), is a two-dimensional polymer built up of a [ZnSO(3)](n) chain evolving around a 2(1) axis and interconnected by a 4,4'-bipyridine spacer. The resulting two-dimensional structures are linked, in turn, by hydrogen bonding mediated by the solvent water molecule. The organic ligand lies on a centre of symmetry located on the mid-point of the bond between the rings, while the solvent water molecule is halved by a twofold axis passing through the O atom.
