A series of gold(I)−carbene complexes of the type [Au(R2-bimy)L] (R = Et, Me; bimy =
benzimidazol-2-ylidene; L = Cl, Br, I, bimy, thiophenolate, phenylacetylide) have been
prepared. These carbene complexes are luminous in acetonitrile solution and in the solid
state with long lifetimes at room temperature. Multiple emissions have been observed for
different R and L. The crystal structure of [Au(Me2-bimy)Cl] shows a relatively short
intermolecular AuI−AuI contact of 3.1664(10) Å and an intermolecular ring π−π interaction
with a ring−ring distance of 3.45 Å. The structure of [Au(Et2-bimy)Cl], however, shows only
intermolecular ring−ring interactions with a distance of 3.53 Å. Crystal structure data
suggest that bimy is a high-trans-influence ligand.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
