catena-Poly[[silver(I)-μ-N-(pyridin-3-ylmeth­yl)pyridine-2-amine-κ(2) N:N′] tri­fluoro­methane­sulfonate]

In the asymmetric unit of the title polymeric complex, {[Ag(C(11)H(11)N(3))](CF(3)SO(3))}(n), there are two Ag(I) atoms, two N-(pyridin-3-ylmeth­yl)pyridine-2-amine ligands (A and B) and two CF(3)SO(3) (−) anions. One Ag(I) atom is coordinated by two pyridine N atoms from two symmetry-related A ligands in a geometry slightly distorted from linear [N—Ag—N = 173.2 (3)°], forming a left-handed helical chain, while the other Ag(I) atom is coordinated by two pyridine N atoms from two symmetry-related B ligands in a bent arrangement [N—Ag—N = 157.1 (3)°], forming a right-handed helical chain. Both helical chains have the same pitch length [10.4007 (7) Å], propagate along the b-axis direction and are alternately arranged via Ag⋯Ag [3.0897 (12) Å] and π–π stacking inter­actions [centroid–centroid distances = 3.564 (7) and 3.518 (6) Å], resulting in the formation of a two-dimensional supra­molecular network extending parallel to the ab plane. Inter­molecular N—H⋯O, C—H⋯O and C—H⋯F hydrogen-bonding inter­actions occur between the helical chains and the anions.
