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.
标题化合物Au₂(C₂₆H₂₄P₂)₂₂·2CH₃CN包含一个环状阳离子，其分子内金-金相互作用较短，键长为2.9220(3) Å。三氟甲磺酸根阴离子和乙腈溶剂分子位于由沿晶体学c轴排列的复合阳离子形成的通道中。每个抗衡阴离子还与1,2-双(二苯基膦基)乙烷(dppe)配体的一个亚甲基H原子形成C-H⋯O接触；还观察到另一个涉及芳香族H原子的C-H⋯O接触。
