XeF2 as a ligand to a metal center, an interesting field of noble gas chemistry
Abstract This paper presents a brief overview of the coordination chemistry with XeF 2 as a ligand to metal centers. A systematic review of the compounds according to their oxidation state is given. Compounds with the metal in the oxidation state II represent the largest group with the highest structural variety and therefore a comparison of compounds with a similar ionic radius is presented. Single-crystal data of recently prepared mercury compounds with the composition [Hg(XeF 2 ) 5 ](AF 6 ) 2 (A = P, As, Sb) are included. All three compounds are structurally related with bridging XeF 2 molecules connecting the mercury atoms into chains.
