Reduction of Cp*(^TrippTerN)UI with KC₈ generates (KCp*(^TrippTerN)UI)₂, the first example of a trivalent uranium imido, a previously elusive species, which are commonly unstable. Experimental and computational results indicate that the K⁺ coordination is responsible for this isolable U(III) monoimido complex.
