Abstract: The asymmetric unit in the polymeric title compound, [Ag(C₁₂H₁₀N₄)]_n·nPF₆·nC₂H₃N, comprises an Ag cation, two half 3-pyridinealdazine (3-PA) molecules, each disposed about a centre of inversion, a hexafluoridophosphate anion and an acetonitrile solvent molecule. The Ag atoms bond to two N atoms and the bridging 3-PA ligands lead to the formation of zigzag chains that are linked into a layer structure via weakly bridging acetonitrile molecules and argentophilic interactions [AgAg = 3.2590 (15) Å]. The layers stack along the b axis and are interspersed by layers of hexafluoridophosphate anions. Various C-HF and C-HN interactions help to consolidate the structure.
