Catena-Poly[[silver(I)-?-N-(pyridin-3-ylmeth-yl)pyridine-2-amine-?(2) N:N'] tri-fluoro-methane-sulfonate].

ABSTRACT: In the asymmetric unit of the title polymeric complex, {[Ag(C11H11N3)](CF3SO3)} n , there are two Ag(I) atoms, two N-(pyridin-3-ylmeth-yl)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 ?-? stacking inter-actions [centroid-centroid distances = 3.564?(7) and 3.518?(6)?Å], resulting in the formation of a two-dimensional supra-molecular network extending parallel to the ab plane. Inter-molecular N-H?O, C-H?O and C-H?F hydrogen-bonding inter-actions occur between the helical chains and the anions.
