Iodine fluoride is unstable at room temperature, inter-halogen compound, which consists of the elements fluorine and iodine.

Physical Properties

The bond length of iodine fluoride molecule is about 191 pm.

Chemical Properties

Iodine fluoride is a white powder and stable at temperatures below -78 ° C; above -14 ° C the compound disproportionates into elemental iodine ( I2) and iodine pentafluoride ( IF5 ), a colorless liquid:

Iodine fluoride reacts with water, analogous to all other inter-halogen compounds, with formation of hydrogen halide, in this case, hydrogen fluoride (HF), and hypohalous acid, in this case, hypoiodous acid ( HOI ):

Iodine fluoride is classified in analogy to stable inter-halogen compounds as toxic.

It tends from all Inter halogens most to decay, this is already at very low temperatures. Therefore, it is not possible to accurately determine the physical properties.

Representation

Iodine fluoride can be represented at low temperatures of the elements:

However, the direct reaction of the elements leads to continuing leading fluorination of Iodfluorids easy to Iodtrifluorid.

It can also be prepared by reduction of Iodtrifluorid with elemental iodine in a trichlorofluoromethane suspension in the presence of a catalytic amount of an organic nitrogen base (pyridine, acetonitrile) at - 40 ° C are obtained.

It can not be practically produced purely and proof of connection is very difficult. This is why most properties are unknown. Perhaps it is polymeric.
