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