IodineForLunch noticed an entry for NO3 in his CRC handbook. According to the CRC handbook, NO3 is a bluish gas that decomposes
at room temperature. I proceeded to dig around in one of my inorganic chemistry books, and found something of interest.
Many gas phase reactions of N2O5 depend on dissociation to NO2 and NO3, with the latter then reacting further as an oxidizing agent. These
reactions ar among the better understood complex inorganic reactions. In the N2O5 catalyzed decomposition of ozone, the steady state concentration of
NO3 can be high enough to allow its absorption spectrum to be recorded.
Six-valence nitrogen... insanity...

Now someone come up with a simple laboratory synthesis!

Silent electric discharge in a mixture of NO2 and O2 (excess) under low pressure.
It's only stable below -142°C, so good luck isolating it.
NO3 is an intermediate during the oxidation of NO to NO2.
A dimer form, N2O6, is also known to exist, but I have no information regarding this compound.
Yet another freaky nitrogenoxide is Dinitrosylperoxide, ONO - ONO, which can be synthesized by leading NO into liquid oxygen...

Sorry to reserect this, but... What are the properties of ONO - ONO, I would assume it transforms into 2NO2 before long

This stuff is nice for liquard rocket(proalbe the reason why ICBM missiles use it). Its corrisive has hell, it explodes when mixed with salt water(sub
sank thanks to it), They mix it with hydazine, as soon as these two chems mix the ingnite, saveing alot of space, and they don't need cold storage
like LH2.

No, the chemical you're thinking of is O<sub>2</sub>N-NO<sub>2</sub>. I've never heard of the salt thing.
