Accessing the plus IV Oxidation State in Molecular Complexes of Praseodymium

Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic, Aurélien René Willauer

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 tetraki ...
