X-Ray crystal structure of caesium hydrogen bis(monofluorosulphate), Cs⁺[O₂FSO.H.OSFO₂]^–, with a very short hydrogen bond

Reactions of Bromine Fluoride Dioxide, BrO2F, for the Generation of the Mixed‐Valent Bromine Oxygen Cations Br3O4+ and Br3O6+

“…been observed; [6] the non-symmetric OÀH•••O bridge here is 2.515 long, as compared to 2.410 in Ref. [6].…”

The crystal and molecular structure of gold tris(fluorosulfate)

“…Gold tris(fluorosu1fate) is prepared from gold powder, oxidized by bis(fluorosulfury1) peroxide, S2O6F2 (9) in solution of fluorosulfuric acid, HS03F, as reported previously (30). About 100 mg of the polycrystalline powder, obtained after removal of all volatiles, are filled inside an inert atmosphere box into a glass ampul, about 100 mm long with 10 mm 0.d.…”

The system fluorosulfuric acid (HSO3F) and bis(fluorosulfuryl)peroxide (S2O6F2) — a solution study

“…Alternatively, one may view the strongly basic S03F-as competing effectively with S2O6F2 for HS03F to form solvates. The strength of the S03FP-HS03F interaction is evident from the isolation and structural characterization of solid monosolvates of the type M'[H(SO~F)~] with M' = Na or Cs (32,33). It does seem that the acid strength of a protonic acid or superacid is instrumental in forming stable solutions of S2O6F2.…”

“…The formulation of monosolvated S2O6F2 and S03F' is chosen because for the related S03F-ion such hydrogen bridged solvates are known (32), and in the case of Cs[S03F.HS03F] structurally characterized (33). Solvation of the S03F' radical is seen to increase the lifetime and mobility of this species in HS03F.…”

“…Furthermore, FS02' reportedly has a g value of 2.005 (40). It is more likely that the fluorosulfate radical, just like S03F- (33) and to a lesser extent its dimer S2O6F2, will form a solvate with HS03F which may subsequently (depending on the temperature) undergo ionic dissociation in an analogous manner as suggested for S2O6F2 above:…”
