In accession to compounds area xenon forms a actinic bond, xenon can anatomy clathrates—substances area xenon atoms are trapped by the apparent filigree of addition compound. An archetype is xenon hydrate (Xe·5.75 H2O), area xenon atoms absorb vacancies in a filigree of baptize molecules.103 This clathrate has a melting point of 24 °C.104 The deuterated adaptation of this hydrate has additionally been produced.105 Such clathrate hydrates can action artlessly beneath altitude of aerial pressure, such as in Lake Vostok beneath the Antarctic ice sheet.106 Clathrate accumulation can be acclimated to fractionally distill xenon, argon and krypton.107
Xenon can additionally anatomy endohedral fullerene compounds, area a xenon atom is trapped central a fullerene molecule. The xenon atom trapped in the fullerene can be monitored via 129Xe nuclear alluring resonance (NMR) spectroscopy. Using this technique, actinic reactions on the fullerene atom can be analyzed, due to the acuteness of the actinic about-face of the xenon atom to its environment. However, the xenon atom additionally has an cyberbanking access on the acuteness of the fullerene.108
While xenon atoms are at their arena activity state, they repel anniversary added and will not anatomy a bond. When xenon atoms becomes energized, however, they can anatomy an excimer (excited dimer) until the electrons acknowledgment to the arena state. This article is formed because the xenon atom tends to ample its exoteric cyberbanking shell, and can briefly do this by abacus an electron from a adjoining xenon atom. The archetypal lifetime of a xenon excimer is 1–5 ns, and the adulteration releases photons with wavelengths of about 150 and 173 nm.109110 Xenon can additionally anatomy excimers with added elements, such as the halogens bromine, chlorine and fluorine.111
