Xenon tetrafluoride is one of the few noble gas compounds and one of the first ( 1962) discovered two elements.

Properties

Xenon tetrafluoride has a planar structure and can be obtained by reaction of xenon with fluorine by heating to 400 ° C and pressure ( which by the exergonic reaction 251 kJ per mole of xenon are free) or are prepared by reaction of xenon with oxygen difluoride.

At normal pressure and a temperature of 115.75 ° C, it goes through sublimation directly from solid to gaseous state. The triple point where the three phases, liquid and gas are determined in equilibrium, is at a temperature of 117.10 ° C.

Xenon tetrafluoride is stable under normal conditions, but hydrolyzed on contact with water to Xenontrioxid.
