Xenon difluoride

Fluoride (XeF2) is a thermodynamically stable compound at room temperature and can be prepared simply by heating mixtures of xenon and fluorine at 300-400 °C (570-750 ºF). Fluoride is reduced with hydrogen to form hydrogen fluoride and xenon and its heat of formation measured in this way.
