Aggregation and Redox‐Disproportionation in Tripodal Indium and Thallium Amides: First Characterization of Mixed‐Valent MI/MII Compounds (M = In, Tl)

Aggregation through weak metal–metal contacts as well as redox disproportionations are the chemical characteristics of the metal exchange products of the tripodal tris(lithium amide)s [H3CC{CH2N(Li)SiMe3}3(L)3] (L=dioxane, THF) with MCl (M = In, Tl). These reactions yield the first examples of mixed-valent MI/MII compounds like [H3CC(CH2NSiMe3)3Tl2]2 (see structure on the right).
