The title complex, [Au(2)Cl(2)(C(26)H(21)NP(2))], has an intra-molecular Au⋯Au inter-action of 3.1669 (4) Å, but no inter-molecular Au⋯Au inter-actions in the solid state. The Cl-Au-P bond angle of 176.84 (7)° is slightly distorted from linearity. The P-C bond length to the phenyl group is shorter [1.810 (7) Å] than the P-C bond length [1.876 (7) Å] to the bridging carbon, indicative of the flexibility of the bidentate bite of the ligand. The C-C N fragment is essentially linear at 179.5 (9)° and the C N bond length of 1.125 (11) Å indicates predominantly triple-bond character. In the crystal packing, there are no hydrogen-bonding or aurophilic inter-actions between the mol-ecules.
标题配合物[Au₂Cl₂(C₂₆H₂₁NP₂)]具有3.1669(4) Å的分子内金⋯金相互作用，但在固态中不存在分子间金⋯金相互作用。Cl-Au-P键角为176.84(7)°，略偏离线性。与苯基相连的P-C键长[1.810(7) Å]比与桥连碳相连的P-C键长[1.876(7) Å]短，这表明配体双齿配位的灵活性。C-C≡N片段在179.5(9)°基本呈线性，C≡N键长为1.125(11) Å，主要表现出三键特征。在晶体堆积中，分子间不存在氢键或亲金相互作用。
