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 AgI ion is coordinated by an O3N donor set in a slightly distorted tetrahedral geometry. The AgI 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) , indicating the presence of argentophilic interactions.
