The uranium(IV) terminal oxo species Tp*2U(O) has been synthesized by oxygen-atom transfer from pyridine-N-oxide to Tp*2U(2,2′-bipyridine), a trivalent uranium species with a monoanionic bipyridine ligand. Full characterization of the oxo species using 1H NMR and IR spectroscopies, X-ray crystallography, and computational studies was performed.
