Platinum hexafluoride

<h2 id="synthesis">Synthesis</h2>
<p>PtF6 was first prepared by reaction of fluorine with platinum metal.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a>  This route remains the method of choice.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
</p>
Pt + 3 F2 → PtF6
<p>PtF6 can also be prepared by <a href="/facts/Disproportionation/67QMkXrV">disproportionation</a> of the pentafluoride (<a href="/facts/Platinum_pentafluoride/tvlQUhgE">PtF5</a>), with the tetrafluoride (<a href="/facts/Platinum_tetrafluoride/2WDL4mqw">PtF4</a>) as a byproduct. The required PtF5 can be obtained by fluorinating PtCl2:
</p>
2 PtCl2 + 5 F2 → 2 PtF5 + 2 Cl2
2 PtF5 → PtF6 + PtF4

<p>Platinum hexafluoride can gain an electron to form the <a href="/facts/Hexafluoroplatinate/TNWH9SmX">hexafluoroplatinate</a> anion, PtF−6.  It is formed by reacting platinum hexafluoride with relatively uncationisable elements and compounds, for example with <a href="/facts/Xenon/9E3XR69R">xenon</a> to form "XePtF6" (actually a mixture of XeFPtF5, XeFPt2F11, and Xe2F3PtF6), known as <a href="/facts/Xenon_hexafluoroplatinate/RtRHxpjp">xenon hexafluoroplatinate</a>. The discovery of this reaction in 1962 proved that <a href="/facts/Noble_gas/j0yHMEAE">noble gases</a> form chemical compounds. Previous to the experiment with xenon, PtF6 had been shown to react with oxygen to form [O2]+[PtF6]−, <a href="/facts/Dioxygenyl_hexafluoroplatinate/AUcQD8RL">dioxygenyl hexafluoroplatinate</a>.
