Xenon tetroxide is a yellow solid at low temperature. It has a vapor pressure of about 25 mm-Hg at 0�C. It is unstable at room temperature. The infrared spectrum of the vapor shows it to have tetrahedral symmetry. 
Xenon Suboxides Stable under Pressure.
It is found that the xenon suboxide Xe3O2 is the first compound to become more stable than the elements, at around P = 75 GPa, and an orthorhombic structure is suggested that comprises extended sheets of square-planar-coordinated xenon atoms connected through bent Xe-O-Xe linkages. Expand
ESR examination of XeO4
An ESR examination of XeO4 in the vapor and solid states suggests that the ground state of this molecule is not a spin triplet as has been proposed for this molecule based on a semiempiricalExpand
Molecular Structure of Xenon Tetroxide, XeO4
The molecular structure of XeO4 has been investigated in the gas phase by electron diffraction. The data are completely compatible with the tetrahedral structure proposed from analysis of theExpand
Crystal Structures and Electronic Properties of Cesium Xenides at High Pressures
The discovery of chemical reactivity of the noble-gas Xe at high pressure has reignited great interest in Xe-containing compounds. Here, we have extensively explored the Cs–Xe system at high pressureExpand
Vibrational Investigations of Several Alkali Metal Haloxenates
Several alkali metal haloxenates of the type MXeO3F, where M=K, Rb, Cs, and MXeO3Cl·MCl, where M=Rb, Cs were synthesized. The infrared and Raman data for these salts were obtained at room temperatureExpand
Using recently published approximate SCF wave functions for Xenon, the one-electron molecular orbital energies of xenon tetroxide have been determined in three approximations and within the generalExpand
Vibrational Spectrum and Force Field of Xenon Tetroxide
Infrared and Raman spectra are reported for Xe16O4 and Xe18O4 vapor. The infrared band contours are analyzed to give values for the Coriolis constants and the xenon isotopic frequency shift, andExpand
Ideal gas thermodynamic properties of xenon compounds
The ideal gas thermodynamic functions from 100° to 1500° K have been computed for three fluorides, three oxyfluorides, and three oxides of xenon using the published spectroscopic data. TheExpand
Stability of xenon oxides at high pressures.
Using an ab initio evolutionary algorithm, the existence of thermodynamically stable Xe-O compounds at high pressures is predicted and calculations indicate large charge transfer in these oxides, suggesting that large electronegativity difference and high pressure are the key factors favouring the formation of xenon compounds.

Kinetics and mechanism of the photodecomposition of xenon tetroxide
The of photochemical decomposition of XcO4 under the action of UV-radia(ion in the wavelength range of 200–300 nm was investigated. The quantum yield of the formation of oxygen atoms upon XeO4Expand


Petrology of Venus: Further Deducftons
The carbon dioxide pressure of the atmosphere of Venus may be controlled by one or more of several decarbonation reactions, one of these is the formation of carbonate-rich liquids, in the range of those proposed for the surface of Venus. Expand
