Description
Summary: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.
