Cation–Cation Interactions, Magnetic Communication, and Reactivity of the Pentavalent Uranium Ion U(NtBu)2+

Communication is important: The dimeric bis (imido) uranium complex U (NtBu) (2) (I) (tBu (2) bpy) (2) (see picture; U green, N blue, I red) has cation-cation interactions between U (NR) (2) (+) ions. This f (1) -f (1) system also displays f orbital communication between uranium (V) centers at low temperatures, and can be oxidized to generate uranium (VI) bis (imido) complexes.
