Hexaoxygen difluoride is a binary inorganic compound of fluorine and oxygen with the chemical formula O₆F₂. ^{[1] [2]} The compound is one of many known oxygen fluorides. ^[3]

Synthesis

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. ^[4]

Physical properties

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. ^[4]
