title: Polymeric (mu2-nitrato-kappa2O:O')(mu2-nitrato-kappa2O:O)(mu4-pyridinium-4-thiolato-kappa4S:S:S:S)disilver(I).
abstract: The title compound, [Ag(2)(NO(3))(2)(C(5)H(5)NS)](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 mu(4) bridge, linking four Ag atoms, with Ag-S bond distances of 2.4870 (19), 2.5791 (19), 2.5992 (19) and 2.848 (2) A. The Ag.Ag distances lie in the range 2.889 (2)-3.049 (1) A.
