Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O2F2. It exists as an orange solid that melts into a red liquid at −163 °C (110 K). It is an extremely strong oxidant and decomposes into OF2 and oxygen even at −160 °C (113 K) at a rate of 4% per day: its lifetime at room temperature is thus extremely short.
