The title compound, Au(2)(C(26)H(24)P(2))(2)(2)·2CH(3)CN, comprises a cyclic cation with a short intra-molecular aurophilic inter-action of 2.9220 (3) Å. The trifluoro-methane-sulfonate anions and acetonitrile solvent mol-ecules are located in channels formed by the complex cations that run along the crystallographic c axis. Each counter-anion is also engaged in a C-H⋯O contact with one of the methyl-ene H atoms of a 1,2-bis-(diphenyl-phosphino)ethane (dppe) ligand; another C-H⋯O contact involving an aromatic H atom is also observed.
