Iodyl fluoride


Iodyl fluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula. It is in the form of colorless crystals. Iodyl fluoride features iodine in the oxidation state of +5. The compound was initially synthesized in 1951.

Synthesis

Iodyl fluoride can be decomposed by iodosyl trifluoride heated to in nitrogen. Since this reaction is reversible, the reaction requires constant removal of iodine pentafluoride.
It can also be obtained by dissolving iodine pentoxide,, in anhydrous hydrogen fluoride.

Physical properties

Iodyl fluoride forms colorless crystals of orthorhombic system. Reacts with water.

Chemical properties

Iodyl fluoride is stable in dry air, but slowly hydrolyzes to iodic and hydrofluoric acids in moisture.
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.
