In the title compound, [AgCl(C(2)H(2)N(2)S(2))](n), the Ag(I) ion has a distorted tetra-hedral geometry, defined by two S atoms of two symmetry-related 1,3,4-thia-diazo-lium-2-thiol-ate ligands and two chloride ions. The Ag(I) ions are bridged into a two-dimensional network parallel to the ab plane by chloride ions and thia-diazole ligands. In the network, the Ag(I) ions are separated by 4.0316 (12) Å along the a axis and by 4.8822 (13) Å along the b axis. N-H⋯Cl hydrogen bonds are observed within the network.
