fluorine azide

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.
