Hexafluorophosphazene is an inorganic compound with the formula (NPF
2)
3. It takes the form of a white powder or lumps. It is sensitive to moisture and heat.[1]
Structure
The molecule has a cyclic, unsaturated backbone consisting of alternating phosphorus and nitrogen centers, and can be viewed as a trimer of the hypothetical compound N≡PF
2. Its classification as a phosphazene highlights its relationship to benzene. Hexafluorophosphazene has a hexagonal P
3N
3 ring with six equivalent P–N bonds. Each phosphorus atom is additionally bonded to two fluorine atoms.[citation needed]
The molecule possesses D3h symmetry, and each phosphorus center is tetrahedral.
The P
3N
3 ring in hexachlorophosphazene deviates from planarity and is slightly ruffled (see chair conformation). By contrast, the P
3N
3 ring in hexafluorophosphazene is completely planar.
