Pentaoxygen difluoride is a binary inorganic compound of fluorine and oxygen with the chemical formula O5F2. [1] [2] 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 5:2. [3]
Pentaoxygen difluoride is an oxidizing agent. At 90 K, the compound looks like a reddish-brown liquid and as an oil at 77 K. [3]
At 77 K, the compound is insoluble in liquid N2, soluble in liquid O2 and CH4. At 65 K, it is soluble in liquid OF2. [3]
