Reaction of [(C5Me5M)2(µ-Cl)2Cl2](M = Rh, Ir) with [Pb(SRf)2] gave covalent [(C5Me5)Ir(SRf)2](Rf= C6F4H, 2b-F4), and ionic [(C5Me5)2Rh2(µ-SRf)3][(C5Me5)Rh(SRf)3](Rf= C6F5, 2a-F5), characterised by single crystal X-ray determinations; NMR spectra of 2b-F4 and its analogues are compatible with a retention of the solid state structure in solution for iridium, while those of 2a-F5 and its analogues indicate that the rhodium complexes participate in equilibria: 3[(C5Me5)2Rh(SRf)2]â[(C5Me5)2Rh2(µ-SRf)3][(C5Me5)Rh(SRf)3].
[(C5Me5M)2(µ-Cl)2Cl2](M = Rh, Ir) 与 [Pb(SRf)2] 反应生成了共价的 [(C5Me5)Ir(SRf)2](Rf= C6F4H, 2b-F4) 和离子型的 [(C5Me5)2Rh2(µ-SRf)3][(C5Me5)Rh(SRf)3](Rf=
C6F5, 2a-F5),这些产物通过单晶 X 射线衍射进行了表征;2b-F4 及其类似物的 NMR 光谱与
铱配合物在溶液中保留固态结构的特征相符,而 2a-F5 及其类似物的 NMR 光谱表明
铑配合物参与了平衡反应:3[(C5Me5)2Rh(SRf)2]⇌[(C5Me5)2Rh2(µ-SRf)3][(C5Me5)Rh(SRf)3]。
