Catena-Poly[[(acetonitrile-κN)silver(I)]-di-μ-trifluoromethanesulfonato-κ4O:O′-[(acetonitrile-κN)silver(I)]-μ-tetraphenyldiphosphine-κ2P:P′

Abstract

The silver(I)-based title polymer, [Ag2(CF3SO3)2(C28H26N2P2)]n, has been synthesized and structurally characterized. The compound shows the formation of a centrosymmetric eight-membered Ag/O/S/O/Ag/O/S/O ring situated around an inversion center, with the AgI ions bridged by two trifluoro­methane­sulfonate ions in a staggered conformation. The rings are then linked by tetra­phenyl­diphosphine ligands into a one-dimensional polymer. The rings have an Ag⋯Ag separation of 5.419 (5) Å and are linked by a 2.2206 (15) Å P—P bond. All AgI ions have pseudo-tetra­hedral geometry, with a coordination environment consisting of two O atoms from two symmetry-related trifluoro­methane­sulfonate ions, a P atom from a phosphine ligand and an N atom from an acetonitrile ligand.
