Crystal structure of catena-poly[[silver(I)-μ-N-(pyridin-2-ylmeth-yl)pyridine-3-amine-κ(2) N:N'] tri-fluoro-methane-sulfonate].

ABSTRACT: In the asymmetric unit of the title compound, {[Ag(C11H11N3)]CF3SO3} n , there are two Ag(I) atoms, two N-(pyridine-2-ylmeth-yl)pyridine-3-amine ligands (A and B) and two CF3SO3 (-) anions. Both Ag(I) atoms are bridged by two pyridine N atoms from two symmetry-related A or B ligands, forming right- or left-handed helical chains, respectively. The Ag(I) atom of the right-handed helical chain adopts a slightly distorted linear coordination geometry [N-Ag-N = 170.69 (14)°], while that of the left-handed helical chain adopts a bent geometry [N-Ag-N = 149.42 (14)°]. Both helical chains have the same pitch length [10.8437 (5) Å], propagate along the b-axial direction and are alternately arranged via Ag⋯Ag [3.0814 (5) Å] and π-π stacking inter-actions [centroid-centroid distances = 3.514 (3) and
