The unusual trinuclear Au(III) oxide title complex, Au(3)Cl(6)O(C(21)H(24)N(2))(3)·2[Ag(C(2)F(6)NO(4)S(2))], is the side product of the reaction of [1,3-bis-(1,3,5-trimethyl-phen-yl)imidazol-2-yl-idene]dichloridophenyl-gold(III) with silver bis-(trifluoro-methane-sulfon-yl)imide in the presence of traces of water. In contrast to corresponding Au(I) complexes, the core structure of the title compound is planar. Two silver(I) bis-(trifluoro-methane-sulfon-yl)imide units are loosely bound to the complex cation. Here the silver atoms, disordered over two positions in a 0.870 (2):0.130 (2) ratio, inter-act either with the lone pairs of three chlorine ligands or two chlorine ligands and one edge of the mesityl π-system. The crystal under investigation was a partial racemic twin.
不寻常的三核金（III）氧化物标题配合物Au₃Cl₆O(C₂₁H₂₄N₂)₃·2[Ag(C₂F₆NO₄S₂)]是[1,3-双-(1,3,5-三甲基苯基)咪唑-2-亚基]二氯苯基金（III）与双（三氟甲烷磺酰）亚胺银在痕量水存在下反应的副产物。与相应的金（I）配合物不同，标题化合物的核心结构是平面的。两个银（I）双（三氟甲烷磺酰）亚胺单元松散地结合到配合物阳离子上。在这里，银原子在两个位置上无序分布，比例为0.870（2）:0.130（2），它们与三个氯配体的孤对电子或两个氯配体以及均三甲苯π体系的一条边相互作用。所研究的晶体是部分外消旋孪晶。
