Out of the 14 lanthanide
(Ln) ions, molecular complexes of Ln(IV)
were known only for cerium and more recently terbium. Here we demonstrate
that the +IV oxidation state is also accessible for the large praseodymium
(Pr) cation. The oxidation of the tetrakis(triphenysiloxide) Pr(III)
ate complex, [KPr(OSiPh3)4(THF)3], 1-PrPh, with [N(C6H4Br)3][SbCl6], affords the Pr(IV) complex
[Pr(OSiPh3)4(MeCN)2], 2-PrPh, which is stable once isolated. The solid
state structure, UV–visible spectroscopy, magnetometry, and
cyclic voltammetry data along with the DFT computations of the 2-PrPh complex unambiguously confirm
the presence of Pr(IV).
