Existence of Hyponitrite Molecule Does the hyponitrite molecule exist? I know the hyponitrite ion exists (http://en.wikipedia.org/wiki/Hyponitrite) but what about the molecule? 

I have found no reference to the molecular form on Wikipedia. But it does seem that such a molecule could at least come together through the dimerization of nitric oxide.
Yes, see Structural and Stablity of Nitric Oxide Dimer.

Just don't call it "hyponitrite molecule", it might get offended.
