| Abstract: | The new ternary adducts, UF4O·SbF5·2CH3CN, UF4O·2SbF5·6L, UF5·SbF5· 2L (L = CH3CN or (C6H5)3PO) and UF5·2SbF5·5CH3CN, have been prepared and studied by infrared, 19F n.m.r. and e.s.r. spectroscopy, mass spectrometry, X-ray powder diffraction and chemical analysis. The infrared spectra strongly suggest an ionic formulation with the uranium cationic species preferentially coordinated by the organic ligand. |
