	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 = {Rotational spectra of OC-AuX (X = F, Cl, Br) have been measured in the frequency range 5-21 GHz, using a pulsed jet cavity Fourier transform microwave spectrometer. The molecules were prepared by ablating. Au metal with a Nd:YAG laser and allowing the vapor to react with CO plus a halide precursor contained in the Ar backing gas of the jets. For OC-AuCl and OC-AuBr these are I the first high-resolution spectroscopic measurements; for OC-AuF these are the first observations of any kind. Ail three molecules are linear. Rotational constants, centrifugal distortion constants, and nuclear quadrupole coupling constants have been precisely evaluated. The geometries determined for all three molecules show CO bond lengths close to that of free CO, plus relatively long Au-C bonds. These results are corroborated by ab initio calculations, which have also produced Mulliken populations showing significant sigma -donation from CO to Au, plus some pi -back-donation from An to CO. There are major changes in the Au, Cl, and Br nuclear quadrupole coupling constants when CO bonds to AuX, consistent with the formation of strong Au-C bonds. The structural properties of OC-AuF are somewhat different from those of OC-AuCl and OC-AuBr.},

The acidic media consists of: the Bronsted superacid HSO3F; the Lewis superacid SbF5; and the conjugate superacid HSO3F-SbF5. Derived from these superacids are the very weakly nucleophilic anions SO3F- or Sb2F11- as counterions to stabilize the cations in solids. Finally, stabilization of the highly electrophilic cations by coordination to CO leads to isolable complexes, unprecedented in transition-metal chemistry in their structural, spectroscopic and bonding characteristics.

	abstract = {The syntheses of the binary fluorosulfates, Zr(SO3F), and Hf(SO3F)4, by oxidation of the corresponding metal powders with bis(fluorosulfuryl) peroxide, S2O6F2, in fluorosulfuric acid, HSO3F, are described. The resulting products are white hygroscopic solids which are not sufficiently soluble in HSO3F to allow electrical conductivity and NMR studies or Hammett acidity function (H-0) determinations in order to evaluate their use as Lewis acids in conjugate superacid systems. Oxidation of titanium under similar conditions resulted in the formation of a greenish-yellow resin-like material of limited thermal stability with the approximate composition Ti(SO3F)4. However, infrared spectra indicated the presence of small amounts of HSO3F. In addition, the solvolysis of ZrCl4 in an excess of HSO3F at 25-degrees-C has been investigated as a potential route to Zr(SO3F)4. The results indicate that short reaction times of 1-2 d yielded incompletely substituted products of the approximate composition ZrClx(SO3F)4-x (x = 0.22), while prolonged reaction times of 3-4 weeks gave rise to partially decomposed materials of approximate composition ZrO0.5F1.5(SO3F)1.5. The ability of all three tetrakis(fluorosulfato) metallates to act as SO3F- ion acceptors is evident from the isolation of thermally stable salts of the composition Cs2[M(SO3F)6] (M = Ti, Zr or Hf) when the metal oxidation was carried out in the presence of 2 mol equiv. of CsSO3F. All the materials were characterized by their vibrational spectra, which are extremely similar and closely resemble those of previously reported cesium hexakis(fluorosulfato) metallates.},

The shifts in binding energies for the C 1s core electron are compared to those of various fluorinated graphites and to shifts reported previously for related acceptor GICs.
