catena-Poly[[silver(I)-μ-N-(pyridin-3-ylmeth­yl)pyridine-2-amine-κ²N:N′] tri­fluoro­methane­sulfonate]

In the asymmetric unit of the title polymeric complex, {[Ag(C₁₁H₁₁N₃)](CF₃SO₃)}_n, there are two Ag^I atoms, two N-(pyridin-3-ylmeth­yl)pyridine-2-amine ligands (A and B) and two CF₃SO₃⁻ 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.

In the binuclear title compound, [Ag₂(C₁₁H₁₁N₃)₂](ClO₄)₂·2C₂H₆SO, the complex cation is centrosymmetric, with the unique Ag^I cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridine-2-ylmeth­yl)pyridine-3-amine ligands in a geometry slightly distorted from linear [N—Ag—N = 170.78 (9)°], resulting in the formation of a 16-membered cyclic dimer. The two pyridine rings coordinating to the Ag^I atom are almost perpendicular to each other [dihedral angle = 87.73 (10)°]. Inter­molecular Ag...O inter­actions [3.149 (3) and 2.686 (3) Å], N—H...O and C—H...O hydrogen bonds and C—H...π inter­actions between the cyclic dimers and the anions or the solvent mol­ecules lead to the formation of a three-dimensional supra­molecular network.
