Bottom Line: Each Ag(I) ion is coordinated by two N atoms from two L ligands in a distorted linear geometry [N-Ag-N = 174.70 (19)°].Each L ligand bridges two Ag(I) ions, thus forming polymeric helical chains propagating in [010].In the crystal, Ag⋯Ag [3.3369 (10) Å] and π-π inter-actions between the aromatic rings [centroid-to-centroid distance = 3.676 (4) Å] link these chains into layers parallel to (10-1).

ABSTRACT
The asymmetric unit of the title compound, {[AgL]·BF4·0.5CH3OH} n , L = N-(pyridin-4-ylmeth-yl)pyridine-3-amine, C11H11N3, contains one Ag(I) ion, one ligand L, one tetra-fluorido-borate anion disordered over two orientations in a 0.669 (13):0.331 (13) ratio and one half of a methanol solvent mol-ecule situated on an inversion center. Each Ag(I) ion is coordinated by two N atoms from two L ligands in a distorted linear geometry [N-Ag-N = 174.70 (19)°]. Each L ligand bridges two Ag(I) ions, thus forming polymeric helical chains propagating in [010]. In the crystal, Ag⋯Ag [3.3369 (10) Å] and π-π inter-actions between the aromatic rings [centroid-to-centroid distance = 3.676 (4) Å] link these chains into layers parallel to (10-1). Ag⋯F and weak N(C)-H⋯F inter-actions further consolidate the crystal packing.

A view of the mol­ecular structure of the title compound with the atom numbering. Displacement ellipsoids are drawn at the 30% probability level. The F atoms of the tetra­fluorido­borate group are disordered over two sets of sites with refined site-occupancy factors of 0.669 (13) (part A) and 0.331 (13) (part B). The disordered methanol solvent mol­ecule is omitted for clarity. [Symmetry codes: (i) − x + , y − , − z + ; (ii) − x + , y + , − z + .]

Mentions: The mol­ecular components of the title structure are shown in Fig. 1 ▸. The asymmetric unit consists of one AgI ion, one L ligand, one tetra­fluorido­borate anion and one half of a methanol mol­ecule. Each AgI ion is coordinated by two pyridine N atoms from two symmetry-related ligands in a geometry which is slightly distorted from linear [N1—Ag1—N3 = 174.70 (19)°], forming an infinite helical coordination polymer. The helical chain propagates along [010] (Fig. 2 ▸) with a pitch length of 15.6485 (14) Å, shorter than that [16.7871 (8) Å] of the nitrate-containing AgI coordination polymer reported by Moon et al. (2014 ▸). The two pyridine rings coordinating the AgI ion are tilted by 13.8 (3)° with respect to each other. The two pyridine rings in the L ligand are almost perpendicular, the dihedral angle between their mean planes being 89.34 (15)°.
