Intercalation reactions of the neptunyl(vi) dication with hydrogen uranyl phosphate and hydrogen neptunyl phosphate host lattices. Technical report
The hydrated layered solids, hydrogen uranyl phosphate. HUO/sub 2/PO/sub 4/, HUP, and its isostructural neptunyl analog, HNpO/sub 2/PO/sub 4/, HNPP, can be intercalated with UO/sub 2/(2+) and NPO/sub 2/(2+) 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 UO/sub 2/(2+) and of HNPP with NPO/sub 2/(2+) lead to hydrated layered solids, (UO/sub 2/)3(PO/sub 4/)/sub 2/, UP, and (NPO/sub 2/)/sub 3/(PO/sub 4/)/sub 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-intercalation reactions (UO/sub 2/(2+) into HNPP; NPO/sub 2/(2+) into HUP) also proceed under stoichiometric conditions.
