| Abstract: | The synthesis of the title compounds by a variety of routes is described. These routes involve the oxidation of antimony(III)fluoride by bis(fluorosulfuryl)peroxide and the use of non-statistical ligand redistribution reactions. Complex formation with ClO2SO3F leads to ClO2[SbFn(SO3F)6-n], with n=3 or 4. Polarized Raman data and low temperature infrared data are reported. All antimony(V)fluoride-fluorosulfates are found to have fluorosulfate bridges with SbF3(SO3F)2 and SbF4(SO3F) being polymers. Ionic formulations for the ClO+2 complexes are again based on vibrational spectra. |
