Charge balance on Linear N₈

Should N≡N⁺)-N⁻-N=N-N⁻-N≡N

be N≡N⁺-N⁻-N=N-N⁻-N⁺≡N?

As written in the article it seems to have a net negative charge (and perhaps 1 more parenthesis than it should).--Wikimedes (talk) 04:12, 1 May 2020 (UTC)[reply]

η-N₂

I've seen one reference in this article (https://en.wikipedia.org/wiki/Solid_nitrogen#Related_substances under Helium) and another vague reference in a phase diagram I founded on the internet (https://courses.grainger.illinois.edu/phys466/fa2020/projects/2000/team4/Intro.html) to an "η-N₂" I don't know if this is another name for one of the phases mentioned on this page or if it is a completely different phase, but I think it would be good if the meaning of this term were clarified somewhere in this article. — Preceding unsigned comment added by DubleH (talk • contribs) 04:53, 2 December 2020 (UTC)[reply]

I have added in a section. The article about the helium compound does call it η-N₂, but that is misleading, as it is not made of N₂ molecules, but is in an amorphous state. So I have called it η-N, the reference I used calls it the η phase. Graeme Bartlett (talk) 11:22, 2 December 2020 (UTC)[reply]
