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 Ag^I 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 AgAg separation of 5.419 (5) Å and are linked by a 2.2206 (15) Å P-P bond. All Ag^I 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.
