Xenon difluoride is a white crystalline solid with an unpleasant odor. One of the first compounds to be prepared from "inert" gases, it was synthesized by the low-pressure photochemical reaction of xenon and fluorine by J. L. Weeks, C. L. Chernick, and M. S. Matheson in 1962. The same year, R. Hoppe and co-workers produced it via electrical discharge. XeF2 is a strong fluorinating agent.

Xenon difluoride1 (XeF2) is a white crystalline solid with an unpleasant odor, in 1962 it became one of the first compounds to be prepared from “inert” gases. Since then, it has been widely studied and incorporated into larger molecules. Earlier this month, Gary J. Schrobilgen and co-workers at McMaster University (Hamilton, ON) reported the synthesis of coordination complexes of XeF2 with the bromyl cation2 (BrO2+), such as [BrO2(XeF2)2][SbF6]. The authors described the properties of the complexes, including their coordination chemistry.
