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

A new series of layered organically templated uranium(IV ) fluorides has been exclusively synthesized under hydrothermal conditions. The unprecedented materials contain [U₂F₁₀]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.
