title: Poly[(μ(4)-5-bromo-pyridine-3-sulfonato)-silver(I)].
abstract: The silver(I) complex, [Ag(C(5)H(3)BrNO(3)S)](n), was obtained by reaction of AgNO(3) and 5-bromopyridine-3-sulfonic acid. The Ag(I) ion is coordinated by an O(3)N donor set in a slightly distorted tetra-hedral geometry. The Ag(I) ions are linked by μ(4)-5-bromo-pyridine-3-sulfonate ligands, forming a layer parallel to (100). The layers are further connected via C-H⋯Br hydrogen-bonding inter-actions into a three-dimensional supra-molecular network. The Ag⋯Ag separation is 3.0159 (6) Å, indicating the presence of argentophilic inter-actions.
