Xenon oxytetrafluoride (XeOF
4) is an inorganic chemical compound. It is an unstable colorless liquid[2][3] with a melting point of −46.2 °C (−51.2 °F; 227.0 K)[4] that can be synthesized by partial hydrolysis of XeF
6, or the reaction of XeF
6 with silica[3] or NaNO
3:[5]
- NaNO
3 + XeF
6 → NaF + XeOF
4 + FNO
2
A high-yield synthesis proceeds by the reaction of XeF
6 with POF
3 at −196 °C (−320.8 °F; 77.1 K).[6]
Like most xenon oxides, it is extremely reactive, and it hydrolyses in water to give hazardous and corrosive products, including hydrogen fluoride:
- 2 XeOF
4 + 4 H
2O → 2 Xe + 8 HF + 3 O
2
In addition, some ozone and fluorine is formed.
