Catena-poly[[(trifluoromethanesulfonato-kappaO)silver(I)]-mu-di-2-pyridylamine-kappa2N2:N2'], a chain polymer with short Ag...C contacts.

The title compound, [Ag(CF3O3S)(C10H9N3)]n, is a chain polymer in which neighbouring monomeric units are related by a glide plane. The silver centre is four-coordinate; the donor atoms are one trifluoromethanesulfonate O atom and one pyridine N atom from each of two symmetry-related dipyridylamines, and an additional and unexpected Ag...C contact [2.6464 (16) A] is observed to a pyridine C atom. The chains are reinforced by one classical N-H...O and two 'weak' C-H...O hydrogen bonds.
