catena-Poly[[[(2-pyridone-κO)silver(I)]-μ-2-pyridone-κO:O] hexa-fluorido-phosphate].

The asymmetric unit of the polymeric title salt, {[Ag(C(5)H(5)NO)(2)]PF(6)}(n), comprises an Ag(I) cation (located on a twofold axis), two 2-pyridone ligands (with distinct coordination modes), and half a PF(6) (-) anion (situated on a centre of inversion). The Ag(I) atom is in an approximately octa-hedral AgO(6) coordination geometry, which is stabilized by intra-molecular N-H⋯O hydrogen bonds. The result of the bridging mode of the 2-pyridone ligand is the formation of a supra-molecular chain along the c axis; these are consolidated in the crystal by C-H⋯F inter-actions.
