Crystal structure of an Ag^I inter-calation compound: catena-poly[[silver(I)-?-N-(pyridin-3-ylmeth-yl)pyridin-3-amine-?²N:N'] hexa-fluorido-phosphate aceto-nitrile disolvate].

ABSTRACT: The asymmetric unit in the title compound, [Ag(C₁₁H₁₁N₃)]PF₆·2CH₃CN or {[AgL]·PF₆·2CH₃CN} _n , L = N-(pyridin-3-ylmeth-yl)pyridin-3-amine, comprises one Ag^I atom, one L ligand, two aceto-nitrile solvent mol-ecules and one PF₆^- anion disordered over two orientations in a 0.567?(11):0.433?(11) ratio. Each Ag^I atom is coordinated by two pyridine N atoms from two L ligands in a slightly distorted linear coordination geometry [N-Ag-N = 170.55?(8)°]. Each L ligand bridges two Ag^I ions, resulting in the formation of a zigzag chain propagating along the [101] direction. In the crystal, Ag?Ag contacts [3.3023?(5)?Å] and inter-molecular ?-? stacking inter-actions [centroid-to-centroid distance = 3.5922?(15)?Å] between the pyridine rings link these chains into a corrugated layer parallel to the ([Formula: see text]01) plane. The layers are stacked with a separation of 10.4532?(5)?Å, and aceto-nitrile solvent mol-ecules and PF₆^- anions as guests are inter-calated between the layers. The layers are connected through several N/C-H?F hydrogen bonds and P-F?? inter-actions [F?ring centroid = 3.241?(8)?Å] between the layer and the inter-calated guests and between the inter-calated guests, forming a three-dimensional supra-molecular network.
