Xenon tetrafluoride physical properties

Physical properties of the Xe-PtFt adduct.—The adduct is yellow when deposited in thin films but in bulk is deep red. The solid becomes glassy in appearance when heated to 115°, but does not melt below 165°, when it decomposes to produce xenon tetrafluoride. X-ray powder photographs of the adduct of composition XePtFe show no diffraction pattern. Complex patterns are observed with samples of material richer in platinum. The plasticity of the material made the preparation of good powder samples difficult. Even well-cooled samples did not grind well. 

In another investigation of the comparative value of lipid and hydration hypotheses (Eger et aL 1969), the minimal anaesthetic concentrations of the following agents were plotted against the relevant physical properties carbon tetrafluoride, sulphur hexafluoride, nitrous oxide, xenon, cyclopropane, fluorexene (trifluoroethyl vinyl ether), diethyl ether, enflurane (see above), halothane, chloroform, and methoxyflurane (see above). (These anaesthetics have been arranged here in order of increasing lipid/water solubility.) The results of this study showed an excellent correlation between...
