I've seen so many compounds containing xenon, and xenon was mostly the central atom, and if we had 2 xenons they would never bond directly to each other. I was curious if it is possible to have for example 2 xenons in a compound that are bonded directly to each other?




One example is the $\ce{Xe2+}$ cation. Quoting from the abstract of [Formation of the dixenon cation, $\ce{Xe2+}$, in fluoroantimonate(V) media by oxidation–reduction methods: spectroscopic properties of the ion](http://dx.doi.org/10.1039/c39780000502)
