Synthesis and Characterization of [XeOXe]2+ in the Adduct‐Cation Salt, [CH3CN‐ ‐ ‐XeOXe‐ ‐ ‐NCCH3][AsF6]2

Abstract Acetonitrile and [FXeOXe‐ ‐ ‐FXeF][AsF 6 ] react at −60 °C in anhydrous HF (aHF) to form the CH 3 CN adduct of the previously unknown [XeOXe] 2+ cation. The low‐temperature X‐ray structure of [CH 3 CN‐ ‐ ‐XeOXe‐ ‐ ‐NCCH 3 ][AsF 6 ] 2 exhibits a well‐isolated adduct‐cation that has among the shortest Xe−N distances obtained for an sp‐hybridized nitrogen base adducted to xenon. The Raman spectrum was fully assigned by comparison with …
