Title: A Linear trans -Bis(imido) Neptunium(V) Actinyl Analog: NpV (NDipp)2 ( tBu2 bipy)2Cl (Dipp = 2,6- i Pr2C6H3)

Abstract

We present the discovery that imido analogs of actinyl dioxo cations can be extended beyond uranium into the transuranic elements. Synthesis of the Np(V) complex, Np(NDipp)2(tBu2bipy)2Cl (1), is achieved through treatment of a Np(IV) precursor with a bipyridine co-ligand 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.
