NO2 and ozone indeed are said to react with each other, giving N2O5 (some textbooks even claim further oxidatin to NO3, but the latter is
questionable). I do not know, however, how fast this reaction is. I have no personal experience with it.
Another route to N2O5 is reaction of fuming white nitric acid with P4O10 and distilling at reduced pressure. N2O5 is not very stable and I have read
somewhere that it decomposes in a month or so, when stored at room temperature. Are you planning to ampoule this solid? If so, I strongly advice you
not to do so. N2O5 decomposes to NO2 and O2 and especially the O2 will give a very high pressure in the ampoule.
Of course, if you want to make N2O5 for certain syntheses or for chemical demonstrations, then that would be great and I would love to see your
results shared over here.
