Abstract

In the cation of the title compound, [Ag(4)(C(2)F(3)O(2))(2)(C(12)H(10)O(2)P)(2)(C(25)H(22)P(2))(2)]·2CH(3)CN, the two independent Ag(+) cations are four-coordinated in a distorted tetra-hedral geometry by one P atom from a bis-(diphenyl-phosphan-yl)methane (dppm) ligand, one O atom from a trifluoro-acetate anion and two O atoms from two diphenyl-phosphinate (dpp) ligands. Two dppm ligands, two dpp ligands and two trifluoro-acetate anions bridge four metal atoms, forming a centrosymmetric tetra-nuclear complex. Intra-molecular C-H⋯O hydrogen bonds and a weak π-π inter-action [centroid-centroid distance = 3.9804 (13) Å] are also observed.
