Crystal structure of an AgIintercalation compound:catena-poly[[silver(I)-μ-N-(pyridin-3-ylmethyl)pyridin-3-amine-κ2N:N′] hexafluoridophosphate acetonitrile disolvate]

Abstract

The asymmetric unit in the title compound, [Ag(C11H11N3)]PF6·2CH3CN or {[AgL]·PF6·2CH3CN}n,L=N-(pyridin-3-ylmethyl)pyridin-3-amine, comprises one AgIatom, oneLligand, two acetonitrile solvent molecules and one PF6−anion disordered over two orientations in a 0.567 (11):0.433 (11) ratio. Each AgIatom is coordinated by two pyridine N atoms from twoLligands in a slightly distorted linear coordination geometry [N—Ag—N = 170.55 (8)°]. EachLligand bridges two AgIions, resulting in the formation of a zigzag chain propagating along the [101] direction. In the crystal, Ag...Ag contacts [3.3023 (5) Å] and intermolecular π–π stacking interactions [centroid-to-centroid distance = 3.5922 (15) Å] between the pyridine rings link these chains into a corrugated layer parallel to the (\overline{1}01) plane. The layers are stacked with a separation of 10.4532 (5) Å, and acetonitrile solvent molecules and PF6−anions as guests are intercalated between the layers. The layers are connected through several N/C—H...F hydrogen bonds and P—F...π interactions [F...ring centroid = 3.241 (8) Å] between the layer and the intercalated guests and between the intercalated guests, forming a three-dimensional supramolecular network.
