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.
Synthesis
[edit]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]
Physical properties
[edit]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]
