μ3-Oxido-tris­{dichlorido13-bis­(135-trimethyl­phen­yl)imidazol-2-yl­idenegold(III)} bis­(trifluoro­methane­sulfon­yl)imide–bis­(trifluoro­methane­sulfon­yl)imide­silver(I) (1/2)

摘要

The unusual trinuclear Au^III oxide title complex, [Au3Cl6O(C21H24N2)3](C2F6NO4S2)·2[Ag(C2F6NO4S2)], is the side product of the reaction of [1,3-bis­(1,3,5-trimethyl­phen­yl)imidazol-2-yl­idene]dichloridophenyl­gold(III) with silver bis­(trifluoro­methane­sulfon­yl)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(trifluoro­methane­sulfon­yl)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, inter­act 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.
