Шаблон:Chembox

Hexafluorophosphazene is an inorganic compound with the formula Шаблон:Chem2. 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 Шаблон:Chem2. Its classification as a phosphazene highlights its relationship to benzene. Hexafluorophosphazene has a hexagonal Шаблон:Chem2 ring with six equivalent P–N bonds. Each phosphorus atom is additionally bonded to two fluorine atoms.Шаблон:Cn

The molecule possesses D3h symmetry, and each phosphorus center is tetrahedral.

The Шаблон:Chem2 ring in hexachlorophosphazene deviates from planarity and is slightly ruffled (see chair conformation). By contrast, the Шаблон:Chem2 ring in hexafluorophosphazene is completely planar.
