Molecular structures,solid-state aggregation and redox transformations of low-valent amido-thallium compounds

摘要

Thallium(I) amides,almost unknown a decade ago,have been a recent focus of main group amide chemistry yielding a large variety of unprecedented structural motifs and patterns of reactivity.The structural chemistry in the solid state was found to be characterised by a clustering of weakly attractive metal-metal interactions as well as metal-arene interactions giving rise to finite or infinite aggregates.Controlled redox disproportionation of thallium(I) amides has provided access the mixed valent compounds including covalently metal-metal bonded Tln-Tlu complexes while stepwise metal exchange reactions have given mixed metal derivatives.
