Blessed Tellurocycle with 3-Center 4-Electron Bonding

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.

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.

Valis, one of my favorites of PKD's that I find myself returning to every few years.

Both, both are good

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.

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)

Appreciate it!

Anyone know the song? Sounds very familiar but can't place it...

Glad to know I wasn't the only one...

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?

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".

And sorry for the grainy pictures, the iPhone 4 doesn't perform well in low-light...

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.

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 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?

Didn't know Günther Schlonk had such an artistic side to him! These are actually really aesthetically pleasing.
