  • Dinitrogen Pentoxide
definition
  • Dinitrogen pentoxide (N2O5) is formed from the reaction of the nitrate radical with nitrogen dioxide. Higher in the atmosphere N2O5 is an effective reservoir for active nitrogen.

Abstract from DBPedia
    Dinitrogen pentoxide is the chemical compound with the formula N2O5, also known as nitrogen pentoxide or nitric anhydride. It is one of the binary nitrogen oxides, a family of compounds that only contain nitrogen and oxygen. It exists as colourless crystals that melt at 41 °C. Its boiling point is 47 °C, and sublimes slightly above room temperature, yielding a colorless gas. Dinitrogen pentoxide is an unstable and potentially dangerous oxidizer that once was used as a reagent when dissolved in chloroform for nitrations but has largely been superseded by nitronium tetrafluoroborate (NO2BF4). N2O5 is a rare example of a compound that adopts two structures depending on the conditions. The solid is a salt, nitronium nitrate, consisting of separate nitronium cations [NO2]+ and nitrate anions [NO3]−; but in the gas phase and under some other conditions it is a covalently-bound molecule.

    五酸化二窒素(ごさんかにちっそ、dinitrogen pentoxide)とは、化学式が N2O5 と表される窒素酸化物である。硝酸の酸無水物に当たり、無水硝酸(むすいしょうさん)とも呼ばれる。窒素の酸化状態は+5価である。
