Dinitrogen Pentoxide, N2Os

This oxide is the anhydride of nitric acid from which it can be prepared by dehydration using a strong dehydrating agent at low temperatures  

As will be discussed later, N205 resembles N02+N03, and as a result it is suggested that a molecule formally containing N02+ and another containing nitrate could produce N205. Thus, we observe that a reaction such as the following does indeed take place  

Dinitrogen pentoxide is a white solid that sublimes at 32 °C. The solid is ionic, N02+N03, with N02+ being linear (Dmh) as a result of it being a 16-electron triatomic species. The N-0 bond length in N02+ is 115 pm, and at low temperatures, the structure of N205 is 

This oxide reacts with water to produce nitric acid  

In keeping with the +5 oxidation state of nitrogen in this oxide, it is also a good oxidizing agent.

Dinitrogen pentoxide, N2Os, decomposes by first-order kinetics with a rate constant of 0.15 s 1 at 353 K. (a) What is the half-life (in seconds) for the decomposition of N2Os at 353 K (b) If [N2O5]0 = 0.0567 mol-L, what will be the concentration of N2Os after 2.0 s (c) How much time (in minutes) will elapse before the N205 concentration decreases from 0.0567 mol-L 1 to 0.0135 mol-L ... 

Energetic materials synthesized with the use of dinitrogen pentoxide (N2Os) technology. 

One reaction that has been studied in detail is the thermal decomposition of gaseous dinitrogen pentoxide, N2Os, to give the brown gas nitrogen dioxide and molecular oxygen ...

When the prefixes tetra, penta, hexa,. .. are followed by the letter o, the a is often dropped. For example, N2Os is often referred to as dinitrogen pentoxide. 

At the cathode nitric acid is reduced to dinitrogen tetroxide and water. The dinitrogen tetroxide is cycled to the anode chamber where it is oxidized to the dinitrogen pentoxide. The anolyte product contains up to 35 wt% N2Os in nitric acid with less than 1 wt% N204. 

Dinitrogen pentoxide readily forms nitronium salts. As mentioned, Weber [27] and other authors [28-31] obtained a number of sulphates of NO. Bachman and Dever [45] prepared a complex with BF3 which most likely possesses the structure NOi Bp3 0NO7 - Kuhn and Olah [33] obtained nitronium tetrafluoroboiate by adding anhydrous HF as a solvent to N2OS and ... 

Nitrogen forms three common oxides N2O (nitrous oxide), NO (nitric oxide), and NO2 (nitrogen dioxide). It also forms two unstable oxides that we will not discuss, N2O3 (dinitrogen trioxide) and N2O5 (dinitrogen pentoxide).
