The title compound, [Ag(NCS)(C(25)H(22)P(2))](n), contains two Ag(+) ions, two thio-cyanate ions and two bis-(diphenyl-phosphino)methane (dppm) ligands in the asymmetric unit. One of the thiocyanate ions bridges the two Ag(+) ions in a μ(2)-mode from its S atom and the two dppm ligands bridge the silver ions in a μ(1),μ(1) mode. The remaining SCN(-) ion bridges the binuclear units via its N and S atoms, generating a one-dimensional polymer propagating in [01]: the resulting AgP(2)SN and AgP(2)S(2) coordination geometries could be described as distorted tetra-hedral.

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-(diphenyl-phosphino)meth-ane]-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-tetra-silver(I)ditungsten(VI) N,N-dimethyl-formamide disolvate, contains two [WS(4)](2-) anions, four silver cations, three bidentate-bridging bis-(diphenyl-phosphino)methane (dppm) ligands and two N,N-dimethyl-formamide (DMF) solvent mol-ecules. The coordination geometry of each Ag atom is distorted tetra-hedral. 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.
