The use of sterically demanding ligands has been shown to be ideal for stabilizing low oxidation state, low coordinate main group and transition metal complexes. Here we present our initial results from extending our use of bulky terphenyl ligands, substituted bis(imino)pyridines and substituted tacn (tacn = 1,4-diisopropyl-1,4,7-triazacyclononane) ligands to stabilize low oxidation state, low coordinate uranium centers.
