the electronic structure. In particular, the increasing steric bulk of this ligand, on moving from O2– to [NAd]2–, results in increasing U═E distances and E–U–Namide angles. These changes have two principal effects on the resulting electronic structure: (1) the increasing U═E distances decreases the energy of the fσ orbital, which is primarily σ* with respect to the U═E bond, and (2) the increasing
