Novel bonding situations in noble-gas chemistry

We are currently in a much better position to understand the factors underlying noble-gas compound formation. This has recently been accomplished by synthesizing over two dozen new xenon and krypton compounds in which the noble gas is bonded to organic fragments through nitrogen. The ligand groups consist of perfluoropyridines, nitriles and s-trifluorotrizine adducted to the lewis acid cations XeF+ and KrF+.The chemistry represents the first …
