Bis[μ(2)-bis­(diphenyl­phosphan­yl)methane-κ(2) P:P′]bis­(μ(4)-diphenyl­phosphinato-κ(4) O:O:O′:O′)bis­[μ(2)-trifluoro­methane­sulfonato­(0.546/0.454)]-κ(2) O:O′;κ(2) O:O-tetra­silver(I) acetonitrile disolvate

In the centrosymmetric tetra­nuclear title compound, [Ag(4)(C(12)H(10)O(2)P)(2)(CF(3)O(3)S)(2)(C(25)H(22)P(2))(2)]·2CH(3)CN, the Ag(I) atom is coordinated by one P atom from a bis­(diphenyl­phosphan­yl)methane (dppm) ligand, two O atoms from two diphenyl­phosphinate (dpp) ligands and one O atom from a trifluoro­methane­sulfonate (OTf) anion in a highly distorted tetra­hedral geometry. Four Ag(I) atoms are bridged by two dppm ligands, two dpp ligands and two OTf anions, forming a tetra­nuclear complex. An weak intra­molecular Ag⋯Ag [3.2692 (14) Å] inter­action is observed. The OTf anion and one of the phenyl groups in the dppm ligand are disordered over two sets of positions in a 0.546 (4):0.454 (4) ratio. The 0.546-occupied OTf is bonded to two Ag atoms in a μ-(κ(2) O:O′) mode, while the 0.454-occupied OTf is bonded in a μ-(κ(2) O:O) mode. The methyl group of the acetonitrile solvent mol­ecule is also disordered over two positions with equal occupancy factors.
