Bis[μ2-bis(diphenylphosphanyl)methane-κ2P:P′]bis(μ4-diphenylphosphinato-κ4O:O:O′:O′)bis[μ2-trifluoromethanesulfonato(0.546/0.454)]-κ2O:O′;κ2O:O-tetrasilver(I) acetonitrile disolvate

Abstract

In the centrosymmetric tetranuclear title compound, [Ag4(C12H10O2P)2(CF3O3S)2(C25H22P2)2]·2CH3CN, the AgI 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 AgI 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-(κ2O:O′) mode, while the 0.454-occupied OTf is bonded in a μ-(κ2O:O) mode. The methyl group of the acetonitrile solvent molecule is also disordered over two positions with equal occupancy factors.
