The adducts UF2O2*nSbF5 (n=2 or 3) have been obtained as pale green and pale yellow-green solids respectively from the reaction of UF2O2 with SbF5 in HF solvent.The solid adducts have been characterized by observation of reaction stoicheiometries, chemical analyses, and vibrational spectra.An X-ray diffraction study has shown that crystals of UF2O2*3SbF5 are monoclinic, space group P21/n, with unit-cell dimensions a=11.040(7), b=12.438(12), c=12.147(8) Angstroem, β=111.16(20) degree, and Z=4.The structure has been refined by three-dimensional least-squares methods to R=0.0773 for 1613 reflections.The structure is best regarded as a fluorine-bridged network of UF2O2 and SbF5 molecules in which the antimony is surrounded by a distorted octahedron of fluorine atoms and the uranium by a pentagonal-bipyramidal array of five fluorines and two oxygens.Two of the uranium-fluorine distances are long and this means that the structure can also be described in terms of zigzag chains of UO2 groups fluorine-bridged to SbF6 units with Sb2F11 side-chains attached to the uraniums.
