Self‐Assembly of Polyoxo Clusters and Extended Frameworks by Controlled Hydrolysis of Low‐Valent Uranium

Cores for celebration! Hydrolysis of trivalent uranium compounds with a stoichiometric amount of water leads to mixed-valence (UIV/UV) discrete clusters with the U6O8 core and with the unprecedented U12O20 core (see picture, right; U green, O red), and to the assembly of U6O8 clusters into extended 3D networks of zeolite-like topology with nanosized cavities (left; U pink, K violet, O red, F green).
