XeF2 Coordination to a Halogen Center; Raman Spectra (n = 1, 2) and X-ray Crystal Structures (n = 2) of [BrOF2][AsF6]·nXeF2 and [XOF2][AsF6] (X = Cl, Br)

The syntheses and structural characterizations of the [XOF(2)][AsF(6)] (X = Cl, Br) salts and the XeF(2) adduct-salts, [BrOF(2)][AsF(6)].nXeF(2) (n = 1, 2), are described. Although the [XOF(2)][AsF(6)] salts have been known for some time, their crystal structures had not been reported until the present study. The crystal structure of [BrOF(2)][AsF(6)] shows a positional disorder among the oxygen atom and the fluorine atoms. Both ClOF(2)(+) and …
