This question has been somewhat pre-empted by a report of its synthesis! They say "green energy storage material" (not quite verbatim) ... yeah - & superpowerful explosive as well - you can be sure that's going to be it's first use!

But the synthesis is not what I am concerned with here, and does not count towards meeting the purport of this question.

Basically it's a (formerly) hypothetical allotrope of nitrogen with an extremely high heat of formation - puts lead azide in the shade - possibly indeed absolutely the highest heat of formation attainable by any chemically bonded substance atall. But it requires 110GPa & 2000K; and I wondered whether natural conditions could ever possibly arise anywhere such that a piece of this could form in the first place and then survive destruction through it's being so very very brisant ... whether basically there's any piece of it floating around anywhere in space. Obviously if it is somehow formed deep within a body of rock, is it atall plausible that it might somehow be extricated from it without it detonating? Or could some extremely fortuitous constellation of conditions arise whereby it could be formed & not have to be extricated from anything? Is the synthesised piece of this stuff the first that has ever existed?

The guys who synthesised it somehow circumvented the extreme pressure & temperature requirements. After all, CVD diamond is made circumventing the T & P requirements for that substance, and is now a standard (though fabulously expensive) industrial process.

Looks like you basically want to answer your own question, which is allowed, just the question statement should still just be the question itself, and then you write up the answer in response to your own question separately. I'd suggest that you edit your question statement above to just be a question, then you can put your answer to it below. $\endgroup$ – Nat Oct 30 '18 at 10:58
  • $\begingroup$ I'm not qruite sure that's quite so: the question is essentially "might it possibly exist naturally this report (truly remarkable & unexpected by me) is not really comprised in the ambit of the question, and is mentioned here merely as a sort of ... appendix, if you will. Stil, I have only just started here; and please don't take this as a rejection of your advice: I am open to being coached in the etiquette of this forum. $\endgroup$ – AmbretteOrrisey Oct 30 '18 at 11:17

  • $\begingroup$ Generally speaking, if it is formed under certain conditions then it is likely stable under those conditions. Remove it from those conditions though, and all bets are off. The hype in the question is not needed, however... $\endgroup$ – Jon Custer Oct 30 '18 at 12:36

Personally, I would say that there is none of this stuff in nature anywhere in the universe, having thought about it for a while. Except just possibly buried deep down in something - not floating around in space, or lying on the surface of any celestial body. It's said to be exceedingly easily detonated, (although how they calculate these things I don't know - I think the calculation of properties of hypothetical substances is one of those astonishing accomplishments - do they solve the Schroedinger equation for the complete ensemble!?), and space is just too violent a place for such a substance ever to be extricated from the matrix in which it forms without detonating.

  • $\begingroup$ Compounds with a high proportion of nitrogen tend to be vigorously unstable. Derek Lowe wrote an entertaining article on this topic a few years ago: Things I Won’t Work With: Azidoazide Azides, More Or Less $\endgroup$ – PM 2Ring Nov 8 '18 at 5:37
  • $\begingroup$ I thought, what with it being pure nitrogen, if some nitrogen should somehow get trapped in some rock, maybe at first at low enough temperature for it to be solid (& apparently there is ordinary solid nitrogen lying around), then there be accretion on top to the tune of 110 GPa, then somehow it get heated to 2000K (the requisite conditions, according to the theory); and then - and this is the hardest bit - that matrix be everso gently eroded away ... that there just just might be some lying or floating around. $\endgroup$ – AmbretteOrrisey Nov 8 '18 at 6:07
