title: Poly[(μ(2)-4,4'-bipyridine)(μ(2)-3,5-dicarboxybenzenesulfonato)silver(I)].
abstract: In the title compound, [Ag(C(8)H(5)O(7)S)(C(10)H(8)N(2))](n), the Ag atom is tetra-coordinated by two 4,4'-bipydidine (4,4'-bipy) N atoms and two monodentate sulfonate O atoms of the 5-sulfoisophthalic acid (H(3)sip) ligands. Adjacent Ag atoms are bonded through four sulfonate O atoms, forming a dinuclear unit with an Ag⋯Ag separation of 3.384 (5) Å; they are further linked together by the 4,4'-bipy lignds into a chain. Classical inter-molecular O-H⋯O and non-classical intra-molecular C-H⋯O hydrogen bonds are also observed in the two-dimensional supra-molecuar structure.
