It is produced by the chemical reaction of xenon with fluorine: [4] [5] Xe + 2 F 2 → XeF 4. This reaction is exothermic, releasing an energy of 251 kJ/mol. [3] Xenon tetrafluoride is a colorless crystalline solid that sublimes at 117 °C. Its structure was determined by both NMR spectroscopy and X-ray crystallography in 1963.
An unusual ion containing xenon is the tetraxenonogold(II) cation, AuXe 2+ 4, which contains Xe–Au bonds. [25] This ion occurs in the compound AuXe 4 (Sb 2 F 11) 2, and is remarkable in having direct chemical bonds between two notoriously unreactive atoms, xenon and gold, with xenon acting as a transition metal
4) is an inorganic chemical compound. It is an unstable colorless liquid [2] [3] with a melting point of −46.2 °C (−51.2 °F; 227.0 K) [4] that can be synthesized by partial hydrolysis of XeF 6, or the reaction of XeF 6 with silica [3] or NaNO 3: [5] NaNO 3 + XeF 6 → NaF + XeOF 4 + FNO 2. A high-yield synthesis proceeds by the reaction ...

The structure of XeF 6 required several years to establish in contrast to the cases of XeF 2 and XeF 4.In the gas phase the compound is monomeric. VSEPR theory predicts that due to the presence of six fluoride ligands and one lone pair of electrons the structure lacks perfect octahedral symmetry, and indeed electron diffraction combined with high-level calculations indicate that the compound's ...
Xenon difluoride is a powerful fluorinating agent with the chemical formula XeF 2, and one of the most stable xenon compounds. Like most covalent inorganic fluorides it is moisture-sensitive. It decomposes on contact with water vapor, but is otherwise stable in storage.
Chemical structures are presented to help readers understand the nature of the titled material. One can subdivide chemical compounds into two main groups: molecules, which includes most organic, polyatomic gases, and organometallic compounds, and nonmolecular species, which includes most purely inorganic compounds. The structures of many ...
Xenon hexafluoroplatinate is the product of the reaction of platinum hexafluoride with xenon, in an experiment that proved the chemical reactivity of the noble gases.This experiment was performed by Neil Bartlett at the University of British Columbia, who formulated the product as "Xe + [PtF 6] −", although subsequent work suggests that Bartlett's product was probably a salt mixture and did ...
