Chlorine–fluorine exchange in XeF + leads to the orange crystalline salt [XeCl] + [Sb 2 F 11 ] − (see structure), which is stable below −10°C. Thus, the number of known noble gas monohalogen cations is now three and, as calculations show, is approaching the theoretically possible limit. The synthesis of other such compounds—with the exception of ArF + , which remains a formidable task—seems unlikely.
