SYNTHESIS AND VIBRATIONAL-SPECTRA OF THE ANTIMONY(V) FLUORIDE-FLUOROSULFATES SBF3(SO3F)2,SBF4(SO3F) AND SB2F9(SO3F)

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. © 1979.
