Xenon difluoride is a linear molecule with an Xe–F bond length of 197.73 ± 0.15 pm in the vapor stage, and 200 pm in the solid phase. The packing arrangement in solid XeF
These are the starting points for the synthesis of almost all xenon compounds. The solid, crystalline difluoride XeF 2 is formed when a mixture of fluorine and xenon gases is exposed to ultraviolet light. [3] The ultraviolet component of ordinary daylight is sufficient. [4] Long-term heating of XeF 2 at high temperatures under an NiF 2 catalyst ...
Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF 2.The first definitive isolation of the compound was published on 3 March 2007, producing it by the previously-examined route of partial hydrolysis of xenon tetrafluoride.

The synthesis of XeF 2 is an endothermic process which results in a white powder which sublimes at low pressures. [10] (P < 4 Torr) [11] The low vapor pressure allowed early researchers and engineers to use it in comparatively simple set ups. Modern vapour etch tools are more sophisticated and are characterized by the way the gas is feed into ...
It is used as a precursor for synthesis of all tetravalent Xe compounds. [9] Reaction with tetramethylammonium fluoride gives tetramethylammonium pentafluoroxenate, which contains the pentagonal XeF − 5 anion. The XeF − 5 anion is also formed by reaction with cesium fluoride: [12] CsF + XeF 4 → CsXeF 5. Reaction with bismuth pentafluoride ...
A high-yield synthesis proceeds by the reaction of XeF 6 with POF 3 at −196 °C (−320.8 °F; 77.1 K). [6] Like most xenon oxides, it is extremely reactive, and it hydrolyses in water to give hazardous and corrosive products, including hydrogen fluoride: 2 XeOF 4 + 4 H 2 O → 2 Xe + 8 HF + 3 O 2. In addition, some ozone and fluorine is formed.
The best known method of synthesis is the fluorination of diphenyl disulfide with xenon difluoride, but it still only has a 25% yield. [ 3 ] C 12 H 10 S 2 + 5 XeF 2 2 C 6 H 5 SF 5 + 5 Xe {\displaystyle {\ce {C12H10S2 + 5 XeF2 -> 2C6H5SF5 + 5Xe}}}
