Mixed Noble-Gas Compounds of Krypton(II) and Xenon(VI); [F₅ Xe(FKrF)AsF₆ ] and [F₅ Xe(FKrF)₂ AsF₆ ].

ABSTRACT: The coordination chemistry of KrF₂ has been limited in contrast with that of XeF₂ , which exhibits a far richer coordination chemistry with main-group and transition-metal cations. In the present work, reactions of [XeF₅ ][AsF₆ ] with KrF₂ in anhydrous HF solvent afforded [F₅ Xe(FKrF)AsF₆ ] and [F₅ Xe(FKrF)₂ AsF₆ ], the first mixed krypton/xenon compounds. X-ray crystal structures and Raman spectra show the KrF₂ ligands and [AsF₆ ]^- anions are F-coordinated to the xenon atoms of the [XeF₅ ]⁺ cations. Quantum-chemical calculations are consistent with essentially noncovalent ligand-xenon bonds that may be described in terms of σ-
