Intercalation Reactions of the Neptunyl(VI) Dication with Hydrogen Uranyl Phosphate and Hydrogen Neptunyl Phosphate Host Lattices

Abstract

The hydrated layered solids, hydrogen uranyl phosphate. HUO2PO4, HUP, and its isostructural neptunyl analog, HNpO2PO4, HNPP, can be intercalated with UO22+ and NPO22+ ions to yield a family of layered, hydrated solids that have been characterized by X-ray powder diffraction and by infrared, Raman, and electronic spectroscopy. Aqueous reactions of HUP with UO22+ and of HNPP with NPO22+ lead to hydrated layered solids, (UO2)3(PO4)2, UP, and (NPO2)3(PO4)2, NPP; preparation of UP from HUP and of NPP from HNPP can also be effected by thermal decomposition of the parent solids, thus affording a set of self intercalation reactions that are reversible. Cross-inter-calation reactions (UO22+ into HNPP; NPO22+ into HUP) also proceed under stoichiometric conditions. Phosphates, Uranium compounds, Neptunium
