Abstract: In the crystal structure of the title compound, {(C₁₀H₉N₂)[AgI₂]}_n, both the cation and anion adopt chain motifs. A hydrogen bond links the positively charged pyridinium end of one cation to the neutral pyridyl end of an adjacent cation; the anions are bridged by two I atoms into a zigzag chain. The Ag atom in the chain exists in a nearly regular tetrahedral environment, on a special position of site symmetry 2.
