Popis: A volatile uranyl compound UO/sub 2/((CF/sub 3/CO)/sub 2/CH)/sub 2/.THF with a vapor pressure of 0.7 torr at 100/sup 0/C has been prepared. The compound has high thermal stability and is suitable for studies of laser-induced isotope separation. The compound has been characterized by its IR, UV, NMR, fluorescence, and mass spectra and other physical and chemical properties including an X-ray structural determination. The molecule contains a linear uranyl ion equatorially surrounded by a pentagon of oxygen atoms. The chelating anions are tilted slightly in a boatlike configuration from this plane. The crystals are monoclinic,P2/sub 1/c, with a = 8.540 (3) A, b = 9.110 (4) A, c = 28.884 (11) A, ..beta.. = 94.26 (3)/sup 0/, and Z = 4.
