From amido to imido: A dinuclear amido-bridged iridium complex promotes the dehydrogenation of alcohols, affording unusual mixed amido/imido Ir4 and bis(imido) Ir3 clusters. Theoretical calculations suggest that bridging μ-NH2 linkages are crucial to achieve the formation of hydrido amine diiridium species, as a result of a concerted net hydrogen transfer through a proposed eight-membered dimetallacycle.
