Data for: "A Route to Stabilize Uranium(II) and Uranium(I) Synthons in Multimetallic Complexes"

Lowvalent uranium can be stabilized via an unprecedented mechanism involving intramolecular ligand migration:the two-and three-electron reduction of the oxo-bridgedU(IV)/U(IV)complex,[{(Ph3SiO)3(DME)U}2(O)], yields formal “U(II)”/U(IV) and “U(I)”/U(IV) complexes,via ligand migration and formation of uranium-arene δ-bond interactions,that can transfer up to threeelectrons tosubstrates by restoring the original ligand arrangement.
