Aggregation of tripodal thallium(I) amides through weak TlI⋯TlI interactions

Abstract

Metal exchange between the lithium amide MeSi[SiMe₂N-(Li)Bu^t]₃ and TlCl yields the corresponding thallium amide MeSi[SiMe₂N(Tl)Bu^t]₃ 1 which aggregates in the solid through weak attractive Tl⋯Tl interactions to form infinite molecular chains; competing redox chemistry leads to the dimetallated species HC[SiMe₂N(Tl)Bu^t]₂[SiMe₂NHBu^t] 2 in the analogous metal-exchange process involving the trisilylmethane derivative.
