catena-Poly[[[(2-pyridone-κO)silver(I)]-μ-2-pyridone-κ2O:O] hexafluoridophosphate]

Abstract

The asymmetric unit of the polymeric title salt, {[Ag(C5H5NO)2]PF6}n, comprises an AgI cation (located on a twofold axis), two 2-pyridone ligands (with distinct coordination modes), and half a PF6− anion (situated on a centre of inversion). The AgI atom is in an approximately octahedral AgO6 coordination geometry, which is stabilized by intramolecular N—H...O hydrogen bonds. The result of the bridging mode of the 2-pyridone ligand is the formation of a supramolecular chain along the c axis; these are consolidated in the crystal by C—H...F interactions.
