Ethylenediammonium decafluorodineptunate(IV)

T. A. Sullens, P. M. Almond and T. E. Albrecht-Schmitt

Abstract: An organically templated neptunium(IV) fluoride compound, {(C₂H₁₀N₂)[Np₂F₁₀]}_n, has been synthesized under mild hydrothermal conditions. The compound crystallizes in the monoclinic space group C2/c (No. 15). The structure consists of NpF₉ tricapped trigonal prisms connected through edge- and corner-sharing to form infinite two-dimensional [Np₂F₁₀]^2- sheets, that are separated by the ethylenediammonium dications. The C₂H₁₀N₂²⁺ cations form hydrogen-bonding interactions with the [Np₂F₁₀]^2- layers.
