Salts of xenic acid are called xenates, containing the HXeO−
4 anion, such as monosodium xenate. They tend to disproportionate into xenon gas and perxenates:[2]
The energy given off is sufficient to form ozone from diatomic oxygen:
Salts containing the deprotonated anion XeO2−
4 are presently unknown.[2]
