Krypton-oxygen bonds

Kr(OTeF5)2 is the first krypton compound containing a krypton-oxygen bond. It was prepared by the reaction between KrF2 and B(OTeFs)3 at 183-161 K in SO2CIF as solvent. ... 

Use of the teflate ligand permitted the synthesis of the first species containing a krypton-oxygen bond (Sanders, J. C. P. Schrobilgen, G. J. J. Chem. Soc., Chem. Comm. 1989, 1576-1578). The synthesis involved the interaction of KrF2 and B(OTep5)3 at low temperature (-90 to -112 C) in SO2CIF as solvent ... 

Following Bartlett s discovery of xenon hexafluoroplatinate(VI), xenon and fluorine were found to combine to give several volatile, essentially covalent fluorides, and at least one fluoride of krypton has been obtained. From the xenon fluorides, compounds containing xenon-oxygen bonds have been made much of the known chemistry of xenon is set out in Figure 12.1.

Another example of crystals containing more than one component is provided by the clathrates. In clathrates of, 3-quinol, three quinol molecules are hydrogen bonded together to form an approximately spherical cavity of radius 4 A (Figure 15.13). Any molecule of appropriate size such as oxygen, nitrogen, krypton, xenon, methane, sulfur dioxide, or methyl alcohol can be trapped, and if it is not disordered within the clathrate, its location and orientation can be determined in the crystalline state by X-ray diffraction methods. In most cases, when a clathrate is... 

Fourier transform IR measurements were used to investigate PVDF films which had been irradiated by means of heavy ions (krypton ions) and electrons. Irradiation with krypton ions was carried out in the presence of helium, hydrogen, deuterium and oxygen. Triple bonds were characteristic of krypton ion irradiation. Double bonds (isolated and conjugated) occurred with both types of irradiation but concentrations were higher with the krypton radiation. The results, including the role of oxygen on the chemical modifications, were discussed. 36 refs. 

The product is a volatile, colorless solid (Figure 22.52). Since then, a number of noble-gas compounds have been prepared that typically involve bonds to the highly electronegative elements fluorine and oxygen. Most of these are compounds of xenon (see Table 22.12), but a few are compounds of krypton and radon. Recently, an argon compound, HArF, was synthesized as well as compounds of CUO bonded to Ne, Ar, Kr, and Xe. All of these recent compounds were synthesized at very low temperatures.
