So today I suddenly stricken with this structure and started to wonder if this polymeric structure of nitrogen is possible or not? If possible then what's its stability?


I searched CCDC for the infinite structures with the following building block:

enter image description here

where where each vertex contains any non-metal atom linked by any type of bond. The only known crystal structure that would meet these criteria is $\ce{[B12]2[CBC][C2]Mg_{1.42}}$ where $\ce{B12}$ icosahedra are linked via $\ce{B–C}$ and $\ce{B–B}$ bonds forming the moieties of the previously shown topology:

enter image description here
Figure 2. Projection of the $\ce{B25C4Mg_{1.42}}$ structure onto the $0ac$ plane (the block of icosahedra of boron carbide structure is marked by shading).

Unfortunately, no similar structures are found for nitrogen yet. Also, the structural motif breaks on boron clusters, but this is the closest as I was able to get.

    $\begingroup$ After a bit of research i found sciencedirect.com/science/article/pii/S0927025614008209, but ccdc structure of nitrogen isn't possible/found yet $\endgroup$

  • $\begingroup$ @G.OVed Ah, the mighty USPEX – this program predicted numerous structures at extreme conditions. Actually, you can answer your own question with this, I think the article is relevant. $\endgroup$
