The mechanism of Fe induced bond stability of uranyl(v)

Marinella Mazzanti, Farzaneh Fadaei Tirani, Radmila Faizova

The stabilization of uranyl(v) (UO21+) by Fe(ii) in natural systems remains an open question in uranium chemistry. Stabilization of UVO21+ by Fe(ii) against disproportionation was ...

Nitrogen activation and cleavage by a multimetallic uranium complex

Rosario Scopelliti, Marinella Mazzanti, Farzaneh Fadaei Tirani

Multimetallic-multielectron cooperativity plays a key role in the metal-mediated cleavage of N-2 to nitrides (N3-). In particular, low-valent uranium complexes coupled with strong alkali metal reducing agents can lead to N-2 cleavage, but often, it is ambi ...
