Strasser C.E. ; Cronje S. ; Raubenheimer H.G. (2009)


The title compound, [Au2(C26H24P 2)2](CF3SO3)2· 2CH3CN, 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. © 2009 Strasser et al.
