Comment on "Stabilization of Low-Valent Iron(I) in a High-Valent Vanadium(V) Oxide Cluster".

Published in: Angewandte Chemie (International ed. in English) (2019)

A recent Communication in this journal reported the stabilization of low-valent iron(I) in a fully oxidized polyoxovanadate. With no ligand-field argument to support such an assignment, a re-evaluation of the data accompanied by detailed computational analysis reveals the redox chemistry is localized to the polyoxovanadate, and when reduced, instigates a spin transition at iron.
