Other Hexafluoride Compounds
The neutral hexafluorides of other elements are also volatile. These include osmium, iridium, rhodium, ruthenium, rhenium, tungsten, technetium, and uranium. All are aggressive oxidants. Uranium hexafluoride and tungsten hexafluoride are used in the nuclear and microelectronics industries, respectively. In the main group elements, sulfur, xenon, selenium, and tellurium form isolable hexafluorides. Sulfur hexafluoride is so extremely stable, perhaps due to steric effects, that it is used as an inert fluid in transformers. The analogues selenium hexafluoride and tellurium hexafluoride are, however, strongly reactive.
Like the hexafluorides of Mo, Tc, Ru, Rh, W, Re, Os, and Ir, PtF6 is octahedral in both the solid state and in the gaseous state. The Pt-F bond lengths are 185 picometers.

Famous quotes containing the word compounds:
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
