Hexaoxygen difluoride is a binary inorganic compound of fluorine and oxygen with the chemical formula O6F2. The compound is one of many known oxygen fluorides.
The compound can be prepared by electric discharges through the F2—O2 mixture of the certain molar ratio at 60 to 77 K. The ratio is predicted to be 6:2.
Hexaoxygen difluoride is an oxidizing agent. At 60 K, the compound looks like a dark-brown crystalline solid. If slowly warmed, it decomposes to lower oxygen fluorides and ozone. If quickly warmed to 90 K, it explodes, creating O2 and F2.
