title: Bis[μ-bis-(diphenyl-phosphino)methane-κP:P']bis-[(4-toluene-sulfonato-κO)silver(I)] monohydrate.
abstract: The title complex, [Ag(2)(C(7)H(7)O(3)S)(2)(C(25)H(22)P(2))(2)]·H(2)O, was obtained by the reaction of silver toluene-sulfonate with diphenyl-phosphinomethane (dppm) in acetonitrile. There are two unique half-mol-ecules of the complex in the asymmetric unit, together with one water mol-ecule, which is disordered over two positions with site occupancy factors of 0.6 and 0.4. In each centrosymmetric neutral dimeric mol-ecule, two Ag atoms are bridged by a pair of dppm ligands to give an eight-membered Ag(2)P(4)C(2) ring with a distorted AgOP(2) trigonal-planar environment. The Ag-Ag distances of 2.9215 (9) and 3.027 (1) Å indicate a direct bonding inter-action.
