The spectrum of XeO/sub 4/ is reported. The typical isotope pattern of Xe is repeated every 16 mass units up to XeO/sub 4/. The exact mass of the tetroxide was verified further by reference to the spectrum of Hg. The fragmentation pattern varied very little with the energy of the ionizing beam of electrons. The volatility of XeO/sub 4/ was demonstrated by its very rapid distillation when a liquid nitrogen bath was replaced by one of dry ice. (P.C.H.) 
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
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
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
Synthesis of the missing oxide of xenon, XeO2, and its implications for Earth's missing xenon.
Raman spectroscopy and (16/18)O isotopic enrichment studies indicate that XeO(2) possesses an extended structure in which Xe(IV) is oxygen bridged to four neighboring oxygen atoms to give a local square-planar Xe O(4) geometry based on an AX( 4)E( 2) valence shell electron pair repulsion (VSEPR) arrangement.

Electronic Structures of Kryptates and Xenates
THE recent preparation of kryptates1 and xenates2 by Grosse et al. opens a new chapter in rare-gas chemistry. Up to now the compounds that have been made have presented no new problems in chemicalExpand
Synthesis, crystal structure and phase transition of a Xe-N2 compound at high pressure: experimental indication of orbital interaction between xenon and nitrogen.
The van der Waals compound Xe(N2)2 with a C15 Laves structure was successfully synthesised at pressures greater than 4.4 GPa. We found that, at 10 GPa, the structure reversibly transforms from aExpand
Noble-Gas Chemistry
Noble-gas reactivity was discovered just over 50 years ago on 23 March 1962 when Neil Bartlett showed that xenon gas was oxidized by PtF 6 . Pursuant to his discovery, numerous xenon and kryptonExpand
Ultraviolet photolysis studies on XeO4 in noble-gas and F2 matrices and the formation and characterization of a new Xe(VIII) oxide, (η(2) -O2 )XeO3.
The photolytic behavior of the thermochemically unstable xenon(VIII) oxide XeO4 was investigated by UV irradiation in noble-gas and F2 matrices and there is strong evidence for the formation of mobile (1) D excited O atoms in the case of excitation at 365 nm. Expand
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
