Note that "C2h" is the symmetry[1] and "N6" is the chemical formula. Yes, 6 Nitrogen in a line, N-N-N-N-N-N with some weird bounds and internal charges, probably a good candidate to "Things I Won't Work With" in https://www.science.org/blogs/pipeline From the article:

[1] See for example another molecule with a different shape but the same symmetry in https://www.cup.uni-muenchen.de/ch/compchem/geom/sym_C2h.htm...

Isn’t it a ring shape?

No, it's almost linear with a small glitch in the center https://www.nature.com/articles/s41586-025-09032-9/figures/4

That's just 3 nitrogen molecules in a trench coat

I know it's a joke, but recently a coworker showed us a preprint about theoretical calculations of long strings of nitrogen. They are very unestable and almost immediately they split into a bunch of N2 molecules. So "just 3 nitrogen molecules in a trench coat" is a good characterization of the situation.

No, they only mentioned that hexanitrobenzene has too small dissociation energy computed, sadly.
