A tetra­silver(I)ditungsten(VI) cluster with sulfide and bis­(diphenyl­phosphino)methane ligands

The asymmetric unit of the title complex, [Ag(4)W(2)S(8)(C(25)H(22)P(2))(3)]·2C(3)H(7)NO, tris­[μ(2)-bis­(diphenyl­phosphino)meth­ane]-3:6κ(2) P:P′;4:5κ(2) P:P′;5:6κ(2) P:P′-μ(5)-sulfido-2:3:4:5:6κ(5) S-μ(3)-sulfido-1:3:4κ(3) S-tetra-μ(2)-sulfido-1:3κ(2) S;1:4κ(2) S;2:5κ(2) S;2:6κ(2) S-disulfido-1κS,2κS-tetra­silver(I)ditungsten(VI) N,N-dimethyl­formamide disolvate, contains two [WS(4)](2−) anions, four silver cations, three bidentate–bridging bis­(diphenyl­phosphino)methane (dppm) ligands and two N,N-dimethyl­formamide (DMF) solvent mol­ecules. The coordination geometry of each Ag atom is distorted tetra­hedral. Two Ag ions are coordinated by μ(2)-S and μ(5)-S atoms, and by two P atoms from two dppm ligands, while the other two Ag atoms are coordinated by μ(2)-S, μ(3)-S and μ(5)-S atoms, and by one P atom from a dppm ligand.
