For those who care and that I’m not patronizing - this is the same kind of behavior you see in TNT (though way more extreme in this molecule). Basically the bonds in these molecules are so unstable they are teetering at the top of a hill and just need a nudge to roll down that hill and become far more stable and much lower energy nitrogen molecules (N2 as nitrogen a nitrogen molecule, not elemental N on the periodic table). When they roll down that hill they let off a huge amount of energy as the bonds break and reform. That energy can be translated to force, as it does in bombs. Just touching this stuff is enough to trigger the bonds to start breaking in a nasty chain reaction.

Amazing they were able to characterize this stuff (that is get the x-rays, NMR specs, etc). I think the only way this stuff could be useful is if it could be somehow completely immobilized in a liquid or solid until use. Sounds insanely dangerous!
