A Raman spectroscopic study of the XeOF4/XeF2 system and the X-ray crystal structure of α-XeOF4·XeF2

The mixed oxidation state complexes, α-XeOF4·XeF2 and β-XeOF4·XeF2, result from the interaction of XeF2 with excess XeOF4. The X-ray crystal structure of the more stable α-phase shows that the XeF2 molecules are symmetrically coordinated through their fluorine ligands to the Xe(VI) atoms of the XeOF4 molecules which are, in turn, coordinated to four XeF2 molecules. The high-temperature phase, β-XeOF4·XeF2, was identified by low-temperature …
