Abstract: The title complex, [Ag₂(C₇H₇O₃S)₂(C₂₅H₂₂P₂)₂]·H₂O, was obtained by the reaction of silver toluenesulfonate with diphenylphosphinomethane (dppm) in acetonitrile. There are two unique half-molecules of the complex in the asymmetric unit, together with one water molecule, which is disordered over two positions with site occupancy factors of 0.6 and 0.4. In each centrosymmetric neutral dimeric molecule, two Ag atoms are bridged by a pair of dppm ligands to give an eight-membered Ag₂P₄C₂ ring with a distorted AgOP₂ trigonal-planar environment. The Ag-Ag distances of 2.9215 (9) and 3.027 (1) Å indicate a direct bonding interaction.
