Samples have detonated when undisturbed at room temperature.

The dialkali xenates do not appear to exist, as xenate disproportions in more alkaline conditions. When it detonates, it releases xenon and oxygen gas.

Two other short-lived xenon compounds with an oxidation state of +8, XeO3F2 and XeO2F4, are accessible by the reaction of xenon tetroxide with xenon hexafluoride. Xenon trioxide is a strong oxidising agent and can oxidise most substances that are at all oxidisable. Dry crystals react explosively with cellulose. XeO3F2 and XeO2F4 can be detected with mass spectrometry.

Any excess perxenic acid slowly undergoes a decomposition reaction to xenic acid and oxygen: Except where otherwise noted, data are given for materials in their, CS1 maint: multiple names: authors list (, https://en.wikipedia.org/w/index.php?title=Xenon_tetroxide&oldid=960620765, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, This page was last edited on 3 June 2020, at 23:52.

It is a highly reactive compound of xenon.

[8], XeO3 should be handled with great caution.

[4] These are not stable and begin to disproportionate into perxenates (+8 oxidation state) and xenon and oxygen gas. Xenon trioxide reacts with inorganic fluorides such as KF, RbF, or CsF to form stable solids of the form MXeO3F. The perxenates are also compounds where xenon has the +8 oxidation state.

It is a powerful oxidizer.

All eight valence electrons of xenon are involved in the bonds with the oxygen, and the oxidation state of the xenon atom is +8. Xenon trioxide is an unstable compound of xenon in its +6 oxidation state.

Element % O: 26.77: Xe: 73.23: Isotope pattern for XeO 3. The Journal of Physical Chemistry Letters 2014, 5 (24) , 4336-4342. Xenon trioxide is an unstable compound of xenon in its +6 oxidation state.

The HXeO−4 anion is the predominant species in xenate solutions.

Above 25 °C, xenon trioxide is very prone to violent explosion: When it dissolves in water, an acidic solution of xenic acid is formed: This solution is stable at room temperature and lacks the explosive properties of xenon trioxide. It is dangerously explosive upon contact with organic materials. David S. Brock and Gary J. Schrobilgen . Xenon trioxide is an unstable compound of xenon in its +6 oxidation state.

The crystal structure is orthorhombic with a = 6.163 Å, b = 8.115 Å, c = 5.234 Å, and 4 molecules per unit cell.

It is dangerously explosive upon contact with organic materials. When it detonates, it releases xenon and oxygen gas.

It is dangerously explosive upon contact with organic materials.

Synthesis of the Missing Oxide of Xenon, XeO2, and Its Implications for Earth’s Missing Xenon.

It is a yellow crystalline solid that is stable below −35.9 ° C ; above that temperature it is very prone to exploding and decomposing into elemental xenon and oxygen (O 2 ). [6], Hydrolysis of xenon hexafluoride or xenon tetrafluoride yields a solution from which colorless XeO3 crystals can be obtained by evaporation. At temperatures above −35.9 °C, xenon tetroxide is very prone to explosion, decomposing into xenon and oxygen gases with ΔH = −643 kJ/mol: Xenon tetroxide dissolves in water to form perxenic acid and in alkalis to form perxenate salts: Xenon tetroxide can also react with xenon hexafluoride to give xenon oxyfluorides: All syntheses start from the perxenates, which are accessible from the xenates through two methods. One is the disproportionation of xenates to perxenates and xenon: The other is oxidation of the xenates with ozone in basic solution: Barium perxenate is reacted with sulfuric acid and the unstable perxenic acid is dehydrated to give xenon tetroxide:[6]. The density is 4.55 g/cm3.

It oxidises carboxylic acids quantitatively to carbon dioxide and water. It is a very powerful oxidizing agent, and liberates oxygen from water slowly, accelerated by exposure to sunlight.
