Pentaoxygen difluoride is a binary inorganic compound of fluorine and oxygen with the chemical formula O
5F
2.[1][2] The compound is one of many known oxygen fluorides.
Synthesis
The compound can be prepared by electric discharges through the F
2—O
2 mixture of the certain molar ratio at 60 to 77 K. The ratio is predicted to be 5:2.[3]
Physical properties
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 N
2, soluble in liquid O
2 and CH
4. At 65 K, it is soluble in liquid OF
2.[3]
