[9] The nickel is not a catalyst for this reaction; nickel containers are used because they react with fluorine to form a protective, non-peeling layer of nickel(II) fluoride NiF2 on their interior surfaces. Xenontetrafluorid ist eine der wenigen Edelgasverbindungen und eine der zuerst (1962) entdeckten aus zwei Elementen. It has a nauseating odour and low vapor pressure. The XeF 4 (xenon tetrafluoride) molecule is hypervalent with six electron pairs around the central xenon (Xe) atom. [3] It is produced by the chemical reaction of xenon with fluorine, F2, according to the chemical equation:[4][5], This reaction is exothermic, releasing an energy of 251 kJ/mol.[3]. Xenon tetrachloride is an unstable inorganic compound with a chemical formula XeCl 4. Xenontetrafluorid ist unter normalen Bedingungen stabil, hydrolysiert aber bei Kontakt mit Wasser zu Xenontrioxid. Xenon tetrafluoride sublimes at a temperature of 115.7 °C. Molecular weight calculation: 131.293 + 18.9984032*4 ›› Percent composition by element Diffusion of xenon (1); tetrachloromethane (2) January 2007; DOI: 10.1007/978-3-540-49718-9_1648. Xenon tetrafluoride is a chemical compound with chemical formula XeF4. Unlike other noble-gas/halide compounds, it cannot be synthesized by simply combining the elements, by using a more-active halogenating agent or by substitution of other halides on tetrahaloxenon compounds. ›› Xenon Tetrafluoride molecular weight. It is world’s first binary compound discovered. [6][7] The structure is square planar, as has been confirmed by neutron diffraction studies,[8] According to VSEPR theory, in addition to four fluoride ligands, the xenon center has two lone pairs of electrons. [8] Der Xenon-Fluor-Abstand beträgt im gasförmigen Zustand 194 pm, im Kristall 195,3 pm.[9]. These lone pairs are mutually trans. August 2019 um 21:36 Uhr bearbeitet. It was the first discovered binary compound of a noble gas. Its structure was determined by both NMR spectroscopy and X-ray crystallography in 1963. Xenon tetrafluoride hydrolyzes at low temperatures to form elemental xenon, oxygen, hydrofluoric acid, and aqueous xenon trioxide. Xenon tetrachloride is an unstable[1] inorganic compound with a chemical formula XeCl4. It is produced by the chemical reaction of xenon with fluorine, F 2, according to the chemical equation: Four of the pairs are bonding pairs, and two are lone pairs. [6] Durch Wasserstoff wird es zu Xenon und Fluorwasserstoff reduziert. [6] Bei Kontakt mit brennbaren Stoffen, wie Aceton oder Leichtmetallpulver kann die Verbindung explosionsartig reagieren.

It decomposes on contact with light or water vapor but is otherwise stable in storage. According to VSEPR theory, the repulsion between the lone pairs is minimized…
