IntroductionClick to copy section linkSection link copied!Complexes of high-valent uranium (>+4 oxidation state) are commonly observed in linear dioxo (uranyl, [O = Un+=O]m+, n = 5, 6; m = n–4) complexes. (1,2) Aside from uranyl complexes, several U6+ mono-oxo or -imido complexes are known, as well as neutral, pseudo-octahedral hexa-halide, alkoxide, alkyl, and amide complexes.

An imidophosphorane ligand framework provided one of the first structurally authenticated examples of molecular Tb4+,1 and the in situ characterization of Pr4+.2 The tetravalent oxidation state in molecular lanthanide (Ln) complexes has been documented in Tb1, 3 and Pr,2, 4 but remains largely confined to examples of Ce4+.5 Despite the similar thermodynamic accessibility of Pr4+ and Tb4+,5a multiple ligand systems which support isolable Tb4+ complexes yield fleeting Pr4+ complexes, precluding...
