Xenon nitrate
Xenon nitrate is a transient compound made by reacting xenon difluoride with anhydrous nitric acid. Although xenon dinitrate (Xe(NO3)2) has not been isolated and characterised, a related mononitrate, known as xenon fluoride nitrate, has also been made and is more well-studied.
Production
Attempted production has used the reaction:[1][2][3]
- XeF2 + 2 HNO3 → Xe(NO3)2 + 2 HF
This reaction makes a red-brown solid. However, it decomposes spontaneously at 23 °C, turning blue temporarily while doing so:[2]
- Xe(NO3)2 → Xe + O2NOONO2 (an unstable nitrogen peroxide)
Although xenon nitrate is not well-characterized, the mixed nitrate FXeONO2 definitely exists.[1]
