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 [H 3 CC{CH 2 N(Li)SiMe 3 } 3 (L) 3 ] (L=dioxane, THF) with MCl (M = In, Tl). These reactions yield the first examples of mixed‐valent M I /M II compounds like [H 3 CC(CH 2 NSiMe 3 ) 3 Tl 2 ] 2 (see structure on the right).
