Description

Fluorine azide or triazadienyl fluoride FN3 is a yellow green gas composed of nitrogen and fluorine with formula FN3. It is counted as an interhalogen compound, as the azide functional group is termed a pseudohalogen. It resembles ClN3, BrN3, IN3 in this respect. The bond between the fluorine atom and the nitrogen is very weak, leading to this substance being very unstable and prone to explosion. Calculations show the F—N angle to be around 102° with a straight line of 3 nitrogen atoms.
The gas liquifies at –82° and can be turned to a solid at –152°C.
It was first made by John F. Haller in 1942.
