	abstract = {The dynamic CO exchange of the monovalent metal carbonyl cations [Ag((CO)-C-13)](+), [Au((CO)-C-13)(2)](+)-Au((CO)-C-13) SO3F and [Rh((CO)-C-12)(4-x)((CO)-C-13)(x)](+) (x <= 1) in superacidic solutions was studied by variable-temperature C-13 NMR methods. The exchange rates are strongly dependent on the acidity of the solvent, the concentration of metal carbonyl cations and temperature. Whereas a suitable exchange rate of the Ag(I) system is only accessible in magic acid (HSO3F-SbF5), the more stable Au(I) and Rh(I) systems were studied in the less acidic fluorosulfuric acid. Selected solutions of Ag(I), Rh(I) and Au(I) yielded activation barriers Delta G* of 42.7, 43.5, and 56.2 kJ mol(-1) respectively. Copyright (c) 2005 John Wiley \& Sons, Ltd.},

	abstract = {The Bronsted-Lewis superacid HSO3F-SbF5 or "magic acid" is re-investigated by modern F-19 NMR methods over a wide concentration range. The system is found to be considerably more complex than had been assumed previously. A,total of 13 different anions are identified of which only five have previously been identified in magic acid. With increasing SbF5 contents the concentration of monomeric anions like [SbF6](-), [SbF5(SO3F)](-), cis- and trans-[SbF4(SO3F)(2)](-), and mer-[SbF3(SO3F)(3)](-) gradually decreases. Except for [Sb2F11](-), which is present in very small concentrations only the formation of oligomers involves exclusively mu-fluorosulfato bridges. In addition to donor (SO3F)(-) and acceptor (SbF5) complex formation to give [SbF5(SO3F)](-) and possibly ligand redistribution, the solvolysis of SbF5 or SbF4(SO3F) in HSO3F appears to be the principal formation reaction for polyfluorosulfatofluoroantimonate(V) anions. In glass (NMR tubes) the solvolysis product HF is converted to the oxonium ion [H3O](+), which has previously been identified by H-1 NMR and structurally characterized as [H3O][Sb2F11] by us.},
