Poly[(μ2-4,4′-bipyridine)(μ2-3,5-dicarboxybenzenesulfonato)silver(I)]

In the title compound, [Ag(C8H5O7S)(C10H8N2)]n, the Ag atom is tetra­coordinated by two 4,4′-bipydidine (4,4′-bipy) N atoms and two monodentate sulfonate O atoms of the 5-sulfoisophthalic acid (H3sip) ligands. Adjacent Ag atoms are bonded through four sulfonate O atoms, forming a dinuclear unit with an Ag⋯Ag separation of 3.384 (5) A; they are further linked together by the 4,4′-bipy lignds into a chain. Classical inter­molecular O—H⋯O and non-classical intra­molecular C—H⋯O hydrogen bonds are also observed in the two-dimensional supra­molecuar structure.
