Abstract
The soluble reagent indium(I) trifluoromethanesulfonate, InOTf, does not appear to react or interact with ferrocene (Cp 2Fe, Cp = C 5H 5) whereas cobaltocene reacts with InOTf to produce [Cp 2Co] +[OTf] − and indium metal. Unexpectedly, the reaction of InOTf with manganocene results in the formation of the unprecedented salt [In(μ 2,η 5-Cp)In] +[Cp 3In(μ 2,η 1-Cp)InCp 3] −: a form of “Cp 2In” that is characterized by X-ray crystallography. Similarly, the reaction of InOTf with [Cp 2Fe] +[PF 6] − produces Cp 2Fe and “In 4OTf 6” in addition to other products. The unusual structural features and the formation of the new indium-containing products are rationalized.
