3. Oxides and Oxohalides of Xe Three oxides of xenon are known:  xenon trioxide (XeO3) and  xenon tetroxide   (XeO4) both of which are dangerously explosive and powerful oxidizing agents, and  xenon dioxide   (XeO 2 ), which was reported in 2011 with a  coordination number of four. XeO 2  forms when xenon tetrafluoride is poured over ice. Xenon does not react with oxygen directly; the trioxide is formed by the hydrolysis of XeF6. XeO3 is weakly acidic, dissolving in alkali to form unstable  xenate  salts containing the HXeO − 4  anion. These unstable salts easily   disproportionate  into xenon gas and  perxenate   salts, containing the XeO6 4− anion. Barium perxenate, when treated with concentrated   sulfuric acid , yields gaseous xenon tetroxide

4. A number of xenon oxyfluorides are known, including XeOF 2 ,  XeOF 4 , XeO 2 F 2 , and XeO 3 F 2 . XeOF 2  is formed by reacting  OF 2  with xenon gas at low temperatures. It may also be obtained by partial hydrolysis of XeF 4 . It disproportionates at −20 °C into XeF 2  and XeO 2 F 2 .XeOF 4  is formed by the partial hydrolysis of XeF 6 .
