Chlorine Heptoxide structure

Chlorine Heptoxide 

structure

Description

Chlorine oxide, light yellow oily liquid (Cl₂O₇), the molecule has a symmetrical double pyramid structure. It is extremely unstable and easily decomposes explosively when impacted or heated.


colorless, very volatile, oily liquid; explodes violently upon concussion or when in contact with iodine or a flame; preparation: dehydration of HClO4 with phosphorus pentoxide; uses: catalyst [KIR78] [MER06]


Cl2O7 is also known as dichlorine heptoxide. It is obtained as a colorless oily liquid by dehydration of perchloric acid using a strong dehydrating agent such as phosphorus pentoxide, P2O5.


An explosive sensitive to impact or rapid heating. Explodes on contact with iodine. Mixtures with bromine pentafluoride are shock-sensitive explosives. When heated to decomposition it emits toxic fumes of Clí. See also PERCHLORATES
