The synthesis and characterization of novel six- and seven-membered expanded ring N-heterocyclic carbene (NHC) complexes of the general formula [Au(NHC)Cl] are described. The key structural parameters of complexes 1, 2, and 4 have been evaluated by solid-state analysis and by means of the percent buried volume (%V-bur) analysis. Complex 4 is found to demonstrate the largest %V-bur value of any gold(1) NHC complex reported to date, with a value of 52.6. All complexes 1-4 have been evaluated in a preliminary catalytic survey of the hydration of internal alkynes.
