Chemical compound
Iodyl fluoride is an inorganic compound of iodine , fluorine , and oxygen with the chemical formula IO2 F . The compound was initially synthesized in 1951.[ 1]
Synthesis
2IOF3 ⇌ IO2 F + IF5
I2 O5 + HF → IO2 F + HIO3
Physical properties
Iodyl fluoride forms colorless crystals of orthorhombic system .[ 3] Reacts with water.[ 4]
Chemical properties
Iodyl fluoride is stable in dry air, but slowly hydrolyzes to iodic and hydrofluoric acids in moisture.[ 1]
IO2 F + H2 O → HIO3 + HF
The compound reacts with strong fluorinating agents such as bromine trifluoride and selenium tetrafluoride to form iodine pentafluoride . Iodyl fluoride can be reduced to elemental iodine by pure hydrogen peroxide .[ 5] [ 6]
3IO2 F + 4BrF3 → 3IF5 + 2Br2 + 3O2
IO2 F + 2SeF4 → IF5 + 2SeOF2
