text: # Xenon dioxydifluoride
  
  Xenon dioxydifluoride is an inorganic chemical compound with the formula $XeO_2F_2.$ At room temperature it exists as a metastable solid, which decomposes slowly into xenon difluoride, but the cause of this decomposition is unknown.
  
  ## Preparation
  
  Xenon dioxydifluoride is prepared by reacting xenon trioxide with xenon oxytetrafluoride.
