The synthesis of lanthanides, other than cerium, in the oxidation state +IV has remained for a long time a desirable but unmet target. Here we report the third example of a molecular complex of terbium(IV) which was isolated and characterized by EPR, UV-vis spectroscopy, SQUID magnetometry, and cyclic voltammetry. The supporting tetrakis(triphenylsiloxide) ligand environment does not saturate the coordination sphere of Tb(IV) in the six-coordinate complex [TbIV(OSiPh3)4(MeCN)2], 2-TbPh, but 2…

Electrochemical oxidation of terbium(III) in aqueous media: influence of supporting electrolyte on oxidation potential and stability
Apart from the generally dominant trivalent oxidation state, several lanthanides can occur in divalent or tetravalent states as well. Changing the valence state alters the chemical properties and,
Cerium(iv) complexes with guanidinate ligands: intense colors and anomalous electronic structures
The results indicate that incorporating guanidinate ligands into Ce(iv) complexes gives rise to intense charge transfer bands and noteworthy electronic structures, providing insights into the stabilization of tetravalent lanthanide oxidation states.
Electron transfer pathways in photoexcited lanthanide(III) complexes of picolinate ligands.
The obtained values were consistent with electron transfer from the excited antenna to the pyridine providing a previously unexplored quenching pathway that could efficiently compete with energy transfer to the lanthanide.

Monovalent lanthanide(I) in borozene complexes
Lanthanide (Ln) elements are generally found in the oxidation state +II or +III, and a few examples of +IV and +V compounds have also been reported. In contrast, monovalent Ln(+I) complexes remain
Exploring the Oxidation States of Neptunium with Schiff Base Coordination Complexes.
Computational results show that the Np-L covalent interactions in NpIVL2 are similar to those in the NnVIO2L(MeOH) complex, indicating that neither the presence of the axial oxo ligands nor the oxidation state significantly modify the nature of the N p-L bonds.
