Coordination of KrF2 to a Naked Metal Cation, Mg2+

Abstract Examples of coordination compounds in which KrF 2 functions as a ligand are very rare. In contrast, XeF 2 provides a rich coordination chemistry with a variety of main‐group and transition metal cations. The reactions of Mg(AsF 6 ) 2 and KrF 2 in HF or BrF 5 solvent have afforded [Mg(KrF 2 ) 4 (AsF 6 ) 2 ] and [Mg(KrF 2 ) 4 (AsF 6 ) 2 ]⋅2 BrF 5 , respectively, the first examples of a metal cation ligated by KrF 2 . Their X‐ray crystal …
