1:1 and 2:1 adducts of diphosphine ligands R2P(R′)nPR2 (dppm: R = Ph, R′ = CH2, n = 1; dppe: R = Ph, R′ = CH2, n = 2; dppp: R = Ph, R′ = CH2, n = 3; dppb: R = Ph, R′ = CH2, n = 4; dppf: R = Ph, R′ = ferrocenyl, n = 1) with silver(I) methanesulfonate have been synthesized and characterized both in solution (1H, 31P NMR) and in the solid state (IR, single crystal X-ray structure analysis). The two different stoichiometries have been found to depend on the molar ratio of ligand to metal employed and the nature of the diphosphine ligand. In AgO3SMe:dppp,dppb (1:1)2, in the [Ag(P^P)2Ag] arrays, the silver atoms are also bridged by anion oxygen atoms, in disparate fashion commensurate with the different Ag⋯Ag distances.

Abstract:	1:1 and 2:1 adducts of diphosphine ligands R2P(R′)nPR2 (dppm: R = Ph, R′ = CH2, n = 1; dppe: R = Ph, R′ = CH2, n = 2; dppp: R = Ph, R′ = CH2, n = 3; dppb: R = Ph, R′ = CH2, n = 4; dppf: R = Ph, R′ = ferrocenyl, n = 1) with silver(I) methanesulfonate have been synthesized and characterized both in solution (1H, 31P NMR) and in the solid state (IR, single crystal X-ray structure analysis). The two different stoichiometries have been found to depend on the molar ratio of ligand to metal employed and the nature of the diphosphine ligand. In AgO3SMe:dppp,dppb (1:1)2, in the [Ag(P^P)2Ag] arrays, the silver atoms are also bridged by anion oxygen atoms, in disparate fashion commensurate with the different Ag⋯Ag distances.
