Selenium Fluorides.—Two iluorides of selenium have been described, the hexafluoride, SeF6, and the tetrafluoride, SeF4. The former was obtained as a stable gas by the action of fluorine on selenium at 78° C.5 Its boiling-point, melting-point and critical temperature are —84-5° C. (in a sealed tube), —39° C. and +72° C., respectively. The vapour density, 97-28, agrees with the formula SeF8.6 The gas does not attack glass. [Pg.315]

However, high temperatures are not essential to produce unstable, reactive species in the gas phase under matrix conditions. This is exemplified by investigations of the lower sulfur and selenium fluorides. These can be prepared near room temperature and at low pressure by fast reactions between a solid and a precursor (type a) or between a gas and a precursor (type b) ... [Pg.308]

A mixture of lower selenium fluorides is obtained by the reaction between heated selenium (210 °C) and fluorine, highly diluted with argon. FSeSeF and the other species are detected by IR spectroscopy. UV irradiation of matrix-isolated FSeSeF yields thermodynamically less stable Se=SeF2. ... [Pg.4297]
