Abstract: The dinuclear Ag^I phosphine complex [Ag₂(dppp)₂]²⁺ [dppp = 1,3-bis(diphenylphosphino)propane] has been crystallized as the BF₄^- salt, viz. [Ag₂(C₂₇H₂₆P₂)₂](BF₄)₂, in order to reduce the effects of coordination by the anion. The dimeric complex consists of two-coordinate Ag^I centers bridged by dppp ligands. The P-Ag-P bond angle deviates significantly from linearity, with a value of 159.66  (3)°. The Ag-P bond distances are close to being equal, with values of 2.3935  (7) and 2.4016  (7)  Å. The cation has a center of symmetry midway between the two Ag atoms.
