Sterically encumbering mono-isocyanides have been shown to stabilize electron rich, low coordinate transition metal complexes. Utilizing the m-terphenyl isocyanide CNArDipp2, we have synthesized and isolated previously unknown examples of mono-anionic, three coordinate rhodium, [Rh(CNArDipp2)3]K and iridium, [Ir(CNArDipp2)3]K. In this talk we will outline the ability of these molecules to act as potent lewis bases, forming reverse dative interactions with thallium. Furthermore, oxidative addition products of the rhodium complex along with the results of its protonation will be discussed.
