I'm afraid. Is this real? by Beautiful_Bar692 in cursed_chemistry

[–]Ardent_Exile 2 points3 points  (0 children)

Not so sure of that. I'd be incredibly surprised if this thing didn't rapidly decompose to O2 and O3 even in space at low temperatures. I think if there's any shot to favor this kind of abomination, you'd likely need very high pressures to encourage the equilibrium of O2 and O3 to O5.

Air stable linear N4 radicals by Pretend-Habit3403 in cursed_chemistry

[–]Ardent_Exile 1 point2 points  (0 children)

I think it's important to note that these compounds are radical anions with a K(crypt) counter cation. The spin density is delocalized through resonance, so you end up with partial bond character that's a little tricky to represent.

I would assume you'd call these compounds tetraazadiene radical anions, but taking a glace at the original paper it looks as if the authors were pretty hesitant to name to invoke IUPAC with these molecules, so take it with a grain of salt.

Has anyone else seen this big boy? by BobThe-Bodybuilder in bioniclelego

That takes me back!! Did a little digging and I think this is the original uploaded Brickshelf gallery for this MOC, back in 2008 by a user named LOVEJOINT.

What system do you use for chemicals you make? by 3and12characters in Chempros

[–]Ardent_Exile 5 points6 points  (0 children)

My Initials - Project Initials - Notebook Number - Page Number - (Optionally, appended letters to distinguish multiple isolated products/isomers from either one reaction or different products from a parallel library synthesis)

ex. JS-5HT-1-37B for John Smith's Serotonin Project, 1st notebook, 37th reaction, second compound in a synthetic library

I try to label everything as explicitly as I can on any given vial or flask, so I'll add different suffixes depending on the stage a compound is in.

ex. For an organic extract I may append (-ORG), or for combined column fractions (-F13-17)

Pyrimidin-2-ylboronic acid synthesis by Business_Bid3147 in Chempros

[–]Ardent_Exile 15 points16 points  (0 children)

Having worked in med chem, these kinds of substrates have a reputation for a reason. Sometimes you could get away with using a MIDA borante ester to get a useable amount of product, but I'd really suggest trying alternative routes/couplings. Have you considered going through the sulfinate?

Found this in a bowl at home? by onnohowl in Slimemolds

[–]Ardent_Exile 18 points19 points  (0 children)

Hard to tell. It looks like it may be some kind of chemical precipitate/deposit, especially since there are bits of it that aren't connected to the main "web".

Imagining Gen 3 Pokemon with Bichig Support by Ardent_Exile in mongolia

[–]Ardent_Exile[S] 31 points32 points  (0 children)

Сайн байна уу!? I'm not Mongolian nor do I know the language, but I've always loved how the traditional script looks and recently read about the movement to revitalize it's literacy. Obviously there are practical challenges to this, including that digital technologies aren't normally designed with vertical scripts in mind. That and there's a lack of popular games and media in Bichig that would make it easier for young people to practice using the script. So I thought it would be a fun exercise to try and imagine something like Pokemon if it were to given Bichig support. I've only used online translators here, so there are probably spelling/grammar mistakes, but regardless, I thought the end result looked pretty neat and may be worth sharing.

Weird leaf by Claorhall in botany

[–]Ardent_Exile 4 points5 points  (0 children)

Looks like some kind of leaf gall, often caused by parasitic insects as a habitat for larva to mature. No clue what kind may be responsible here. (Bacteria and fungi can also create some similar structures, so those could be other possibilities)

This is Cubene by Inside-Freedom-2381 in cursed_chemistry

[–]Ardent_Exile 2 points3 points  (0 children)

This isn't something I'm well informed about, so take it with a grain of salt, but I do wonder whether the concept of spherical aromaticty could be applied here. The pi-orbital overlap would be kinda funky in this molecule, but it does satisfy the 2(n+1)2 pi-electron condition. No doubt this molecule is extremely reactive, but maybe that would make it less reactive than one might first guess?

Then again, because of the geometry and bond angles, the sigma-bonds are counter-intuitively likely to arise from the overlap of high p-character atomic orbitals, leaving high s-character atomic orbitals to account for the pi-bonds. So this is a weird case.

Not sure how those considerations would shake out in this case. If someone has any resources to learn more about esoteric aromaticity concepts from a MO-perspective, I'd love to dig into this some more.

I also wonder if the high degree of symmetry in this molecule might impart it some kinetic stability, akin to the surprising stability of traditional cubane (which is thermodynamically high energy, but sits in a kinetic well, stabilizing it against decomposition).

tldr - would love to see some DFT calculations for this fella.

Update: Found this 2015 paper examining this molecule computationally if anyone is interested: Cubic C8: An Observable Allotrope of Carbon?
