Magic-number Au11 clusters containing N-heterocyclic carbene (NHC) ligands are prepared by ligand exchange on known phosphine clusters and the introduction of even a single NHC results in improved cluster stability. The use of NHC-containing clusters in the electrocatalytic reduction of CO2 to CO is described and correlates with cluster stability.
