Fluorine azide or triazadienyl fluoride is a yellow green gas composed of nitrogen and fluorine with formula FN3.[1] Its properties resemble those of ClN3, BrN3, and IN3.[2] The bond between the fluorine atom and the nitrogen is very weak, leading to this substance being very unstable and prone to explosion.[3] Calculations show the F–N–N angle to be around 102° with a straight line of 3 nitrogen atoms.[4]

The gas boils at –30° and melts at –139 °C.[5]

It was first made by John F. Haller in 1942.[6]
