A homoleptic η2 hydroxylaminato CeIV complex with S4 symmetry

Article abstract of DOI:10.1039/c4dt00287c

An electron rich, air-stable hydroxylamine ligand and a strongly stabilized cerium(iv) hydroxylaminato complex are described. The synthesis of Ce[η²-ON(^tBu)(2-OMe-5-^tBu-C ₆H₃)]₄ (1) proceeded through a one pot protonolysis and oxidation procedure. Complex 1 crystallized with the molecule in exact S₄ symmetry. The hydroxylaminato ligands were bound in an η² mode that is of interest for potential application in the separations chemistry of rare earth metals. This journal is the Partner Organisations 2014.
