The extremely bulky N-heterocyclic carbene (NHC), ITr, (ITr = [(HCNCPh3)2C:]) featuring sterically shielding umbrella-shaped trityl (-CPh3) substituents was prepared. This NHC features the highest percent buried volume (%Vbur) to date, and was used to form a thermally-stable quasi one-coordinate thallium(I) cation [ITr-Tl]+. This Tl(I) adduct and the corresponding lithium complex [ITr*Li(OEt2)]+ are versatile "all-in-one" transmetalation/ligation reagents for preparing low-coordinate inorganic species inaccessible via pre-existing routes.
