In the title compound, [AgCl(C₂H₂N₂S₂)]_n, the Ag^I ion has a distorted tetrahedral geometry, defined by two S atoms of two symmetry-related 1,3,4-thiadiazolium-2-thiolate 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 thiadiazole 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-HCl hydrogen bonds are observed within the network.
