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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
