The First Organically Templated Layered Uranium(IV) Fluorides: (H3N(CH2)3NH3)U2F10⋅2 H2O, (H3N(CH2)4NH3)U2F10⋅3 H2O, and (H3N(CH2)6NH3)U2F10⋅2 H2O

Abstract

A new series of layered organically templated uranium(IV) fluorides has been exclusively synthesized under hydrothermal conditions. The unprecedented materials contain [U₂ F₁₀ ]^2- anionic layers that are separated by charge balancing cationic templates and occluded water molecules (see structure depicted). The templates can be fully ion-exchanged for a variety of metals (Na⁺ , K⁺ , and Co²⁺ ) at room temperature.
