Bis[μ-bis(diphenylphosphino)methane-κ2P:P′]bis[(4-toluenesulfonato-κO)silver(I)] monohydrate

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.
