Poly[(μ₄-5-bromo­pyridine-3-sulfonato)­silver(I)]

The silver(I) complex, [Ag(C₅H₃BrNO₃S)]_n, was obtained by reaction of AgNO₃ and 5-bromopyridine-3-sulfonic acid. The Ag^I ion is coordinated by an O₃N donor set in a slightly distorted tetra­hedral geometry. The Ag^I ions are linked by μ₄-5-bromo­pyridine-3-sulfonate ligands, forming a layer parallel to (100). The layers are further connected via C—H...Br hydrogen-bonding inter­actions into a three-dimensional supra­molecular network. The Ag...Ag separation is 3.0159 (6) Å, indicating the presence of argentophilic inter­actions.
