Xenon hexafluoride, XeF 6 Index of chemical compounds with the same name This set index article lists chemical compounds articles associated with the same name.
To prevent decomposition, the xenon tetroxide thus formed is quickly cooled into a pale-yellow solid. It explodes above −35.9 °C into xenon and oxygen gas, but is otherwise stable. A number of xenon oxyfluorides are known, including XeOF 2, XeOF 4, XeO 2 F 2, and XeO 3 F 2. XeOF 2 is formed by reacting OF 2 with xenon gas at low temperatures.
The change of Gibbs free energy (ΔG) in an exergonic reaction (that takes place at constant pressure and temperature) is negative because energy is lost (2). In chemical thermodynamics, an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). [1]
The XeF + cation is formed by combining xenon difluoride with a strong fluoride acceptor, such as an excess of liquid antimony pentafluoride (SbF 5): XeF 2 + SbF 5 → XeF + + SbF − 6. Adding xenon gas to this pale yellow solution at a pressure of 2–3 atmospheres produces a green solution containing the paramagnetic Xe +
Xenon hexafluoride is a noble gas compound with the formula XeF 6. It is one of the three binary fluorides of xenon that have been studied experimentally, the other two being XeF 2 and XeF 4. All known are exergonic and stable at normal temperatures. XeF 6 is the strongest fluorinating agent of the series. It is a colorless solid that readily ...
The lighter noble gases xenon and krypton can be made to react with fluorine under special conditions, while argon will undergo chemical transformations only with hydrogen fluoride. [18] Nitrogen, with its very stable triple bonds , requires electric discharge and high temperatures to combine with fluorine directly. [ 19 ]
Due to the instability of xenon(II), it is difficult to synthesize organoxenon compounds by using general organic reagents. Organoxenon compounds are frequently prepared from organocadmium species including Cd(Ar F ) 2 (where Ar F is a fluorine-containing arene ), C 6 F 5 SiF 3 , and C 6 F 5 SiMe 3 (used along with fluoride).
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. [ 6 ] [ 7 ] The structure is square planar , as has been confirmed by neutron diffraction studies. [ 8 ]
