Abstract: In the polymeric title compound, {[Ag(C₁₂H₁₀N₄)](CH₃SO₃)}_n, the Ag atom exists in an almost linear NAgN geometry and the topology of the supramolecular chain is a zigzag. Adjacent chains are linked via weak argentophilic AgAg interactions [3.1402 (8) Å] to form double chains and the anions are associated with this via AgO contacts [2.508 (3) Å]. Layers are formed through C-HO interactions and the layers stack via - interactions [centroid-centroid separation = 3.751 (3) Å].
