Polymeric (μ2‐nitrato‐κ2O:O′)(μ2‐nitrato‐κ2O:O)(μ4‐pyridinium‐4‐thiol­ato‐κ4S:S:S:S)­disilver(I)

The title compound, [Ag₂(NO₃)₂(C₅H₅NS)]_n, was obtained from the reaction of silver nitrate with bis(4‐pyridyl) disufide (4‐PDS) in a mixture of ethanol and water, which suggests that the di­sulfide bond of 4‐PDS can be cleaved under mild conditions. The structure of the title compound is a two‐dimensional infinite array in which the asymmetric unit contains two Ag atoms, a pyridinium‐4‐thiol­ate mol­ecule and two nitrate groups. Each pyridinium‐4‐thiol­ate mol­ecule acts as a μ₄ bridge, linking four Ag atoms, with Ag—S bond distances of 2.4870 (19), 2.5791 (19), 2.5992 (19) and 2.848 (2) Å. The Ag⋯Ag distances lie in the range 2.889 (2)–3.049 (1) Å.
