Abstract

Abstract Compositions of matter are described comprising the intercalation of Lewis bases into the layer lattice structure of UO 2 F 2 or by formation of directed chemical bonds between an electron donor atom of the Lewis base and the uranium ions in UO 2 F 2 . Thermal treatment of these compositions results in the release of the Lewis base unchanged and the recovery of the uranyl fluoride.
