Abstract: The asymmetric unit of the title complex, [Ag4W2S8(C25H22P2)3]·2C3H7NO, tris[2-bis(diphenylphosphino)methane]-3:62P:P';4:52P:P';5:62P:P'-5-sulfido-2:3:4:5:65S-3-sulfido-1:3:43S-tetra-2-sulfido-1:32S;1:42S;2:52S;2:62S-disulfido-1S,2S-tetrasilver(I)ditungsten(VI) N,N-dimethylformamide disolvate, contains two [WS4]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 2-S and 5-S atoms, and by two P atoms from two dppm ligands, while the other two Ag atoms are coordinated by 2-S, 3-S and 5-S atoms, and by one P atom from a dppm ligand.
