Back Cover: Base-Driven Assembly of Large Uranium Oxo/Hydroxo Clusters (Angew. Chem. Int. Ed. 25/2011)
Low-valent uranium clusters provide good models to understand the formation and behavior of UO2 nanoparticles. In their Communication on page 5745 ff., M. Mazzanti et al. present a reproducible method for the synthesis of such clusters. Benzoic acid is used to promote the formation of large oxo–hydroxo clusters, and cluster size can be tuned by the choice of solvent and base, thus leading to a U16 compound that is the largest UIV cluster reported to date.
