Platinum hexafluoride

This compound is the only one known for these elements in this oxidation state it is obtained as a highly-colored solid by the high-temperature reaction between fluorine and the metal. The solid is isostructural with the hexafluorides of osmium and iridium, and the Pt-F distance has been estimated at 1 83 A by extrapolation along the series W-Os-Ir 255). The infrared spectrum has been assigned in Oh symmetry 256) there are no signs of any distortion, as found for example in osmium hexafluoride.

Binary Compounds. Three fluorides, PtF [13455-15-7], PtF [37782-184-8], and platinum hexafluoride [13693-05-5], PtF, are well documented. The last is a powerful oxidi2ing agent and can oxidi2e dioxygen and xenon (235). Two chlorides exist, platiaum dichloride [10025-65-7],...

Platinum hexafluoride does not have many commercial apphcations. It is used as a strong oxidizing agent and can oxidize oxygen from the air. It is used in research. Platinum hexafluoride forms compounds with molecular oxygen and xenon, [02" ][PtF6 ] and XePtFe, respectively. 

Platinum hexafluoride may be prepared by heating platinum with fluorine under pressure. The preparation should be in nickel or Monel apparatus as the compound reacts with glass. 

Platinum hexafluoride is dangerously corrosive. Inhalation of its vapors or skin contact causes serious injury. Also, it can react explosively with a number of substances. 

Although xenon has the stable octet configuration and is thought to be as inert as other noble gases, several xenon compounds have been prepared. The first xenon compound synthesized by N. Bartlett in 1962 was a red sohd, XePtFe, made by the reaction of xenon with platinum hexafluoride undergoing the following oxidation sequence (Cotton, F. A., Wilkinson G., Murillo, C. A. and M. Bochmann. 1999. Advanced Inorganic Chemistry, ed., pp. 588. New York John Wiley Sons) ...

The same authors showed that platinum hexafluoride, which is a somewhat weaker oxidative fluorinating agent than KrF+, can also oxidize NF3, though the yield and purity of the NF4+ fluoroplatinate formed as a dark red solid were low. The pure salt was prepared for purposes of comparison by the thermal reaction at 125°C between NF3, F2, and PtF6. The reaction between NF3 and the hexafluoride was carried out either in HF solution at 25°C or under ultraviolet irradiation in the gas phase, also at ambient temperature. In each case the vibrational spectrum of the product showed the presence of a tetraflu-oroammonium salt, but the product was a mixture of fluoroplatinate and polyfluoroplatinate which could not be purified by extraction with liquid HF.
