The discovery that imido analogs of actinyl dioxo cations can be extended beyond uranium into the transuranic elements is presented. Synthesis of the Np­(V) complex, Np­(NDipp)2(tBu2bipy)2Cl (1), is achieved through treatment of a Np­(IV) precursor with a bipyridine coligand and lithium-amide reagent. Complex 1 has been structurally characterized, analyzed by 1H NMR and UV–vis−NIR spectroscopies, and the electronic structure evaluated by DFT calculations.
