In the crystal structure of the title compound, [Ag3(C9H6N3O3S)3(H2O)2]n, the molecules are linked into three-decked polymeric zigzag chains propagating in [100]. On the middle deck, the Ag atom is five-coordinated by three O atoms from three 4-(3-pyridyl)pyrimidine-2-sulfonate (L) ligands, one of which lies on a mirror plane with the sulfonate group disordered over two orientations in a 1:1 ratio, and two N atoms from two L ligands, which lie on the same mirror plane. On the upper and lower decks, the Ag atom is four-coordinated by an aqua ligand, one O and two N atoms from two L ligands with the pyridyl and pyrimidine rings twisted at 19.8 (2)°. In the polymeric chain, there are π–π interactions between six-membered rings of L ligands from different decks with centroid–centroid distances of 3.621 (7) and 3.721 (3) Å. In the crystal, intermolecular O—H...O hydrogen bonds link further these three-decked chains into layers parallel to (010).
