Bis[-bis(diphenylphosphino)methane-²P:P']bis[(chlorodifluoroacetato-O)silver(I)](Ag-Ag)

K. M. Lo and S. W. Ng

Abstract: The asymmetric unit of the title compound, [Ag₂(C₂ClF₂O₂)₂(C₂₅H₂₂P₂)₂], consists of two half-molecules, each Ag^I ion lying on a center of symmetry. In each complete molecule, two bis(diphenylphosphino)methane ligands bridge two Ag^I ions, which are further coordinated by one chlorodifluoroacetate ligand, giving T-shaped geometries and short intramolecular AgAg distances of 3.1078 (6) and 2.9950 (6) Å. In one molecule, the unique -CF₂Cl group is rotationally disordered over two sites with approximate occupancies of 0.53 and 0.47 for the major and minor components, respectively.
