Dinitrogen pentoxide is a colorless crystalline solid which sublimes without melting at 32.5 °C at atmospheric pressure." Dinitrogen pentoxide is inherently unstable and readily decomposes to oxygen and dinitrogen tetroxide at room temperature as shown in Equation (9.1). The rate of decomposition is temperature dependent with a half-life of 10 days at 0 °C and 10 hours at 20 It is stable for 2 weeks at —20 °C and up to 1 year at temperatures below —60 °C. 

Dinitrogen pentoxide is readily soluble in absolute nitric acid and chlorinated solvents. The polarity of the solvent has a significant effect on the rate of decomposition in solution. The rate is fastest in nonpolar solvents like chloroform and slower in polar solvents like nitromethane. ° The decomposition rate for solutions of dinitrogen pentoxide in nitric acid is very slow and these solutions are moderately stable at subambient temperatures. ...
