"Dissolution" of Indium(I) Iodide: Synthesis and Structural Characterization of the Neutral Indium Sub-Halide Cluster Complex [In6I8(tmeda)4]

The “In” crowd: “Dissolution” of the widely used synthetic reagent indium(I) iodide in tmeda/toluene mixtures (tmeda=N,N,N′,N′‐tetramethylethylenediamine) gives [In6I8(tmeda)4]. Its stability and significant solubility in toluene makes it an alternative reagent for synthetic methodologies employing...

Zusammenfassung:The “In” crowd: “Dissolution” of the widely used synthetic reagent indium(I) iodide in tmeda/toluene mixtures (tmeda=N,N,N′,N′‐tetramethylethylenediamine) gives [In6I8(tmeda)4]. Its stability and significant solubility in toluene makes it an alternative reagent for synthetic methodologies employing InI. DFT studies (see picture) suggest that its deep red‐orange color arises from metal‐based σ→σ* electronic transitions.
