abstract: In the centrosymmetric tetra-nuclear 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-(diphenyl-phosphan-yl)methane (dppm) ligand, two O atoms from two diphenyl-phosphinate (dpp) ligands and one O atom from a trifluoro-methane-sulfonate (OTf) anion in a highly distorted tetra-hedral geometry. Four Ag(I) atoms are bridged by two dppm ligands, two dpp ligands and two OTf anions, forming a tetra-nuclear complex. An weak intra-molecular Ag⋯Ag [3.2692 (14) Å] inter-action 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 mol-ecule is also disordered over two positions with equal occupancy factors.
