Cyclometallation following coordination of anionic and neutral Lewis bases to a uranium(IV) dialkyl complex

The graphical abstract depicts 3 key structures in the manuscript: the unstable trialkyl “ate” complex, the cyclometallated “ate” complex, and the neutral cyclometallated 9-azajulolidine complex. These three structures highlight the strong variation in the orientation of the co-ligands relative to the xanthene backbone of the ligand.234
