Question on a compound's atomic structure

Velzee - 1-3-2016 at 13:59

This is a rather odd request, but I was wondering if there was a chemical which has a similar structure to the radiation hazard symbol (https://en.wikipedia.org/wiki/Hazard_symbol#/media/File:Radi...). The closest I've found so far is that of chromium(VI) peroxide(https://en.wikipedia.org/wiki/Chromium(VI)_oxide_peroxide#/media/File:CrO5-2D.png).

This was just a random question that popped into my head as I began to read the Wikipedia page of CrO5. Thank you all in advance!

Weird question:D, maybe TATP?

Eh, not quite what I'm looking for xP

What exactly were you looking for, apart from what you have already had ?

A chromium compound with six oxygen atoms attached to it, in the shape of the radiation symbol, or something similar. Again, I'm only basing this off aesthetics.

P.S. Long time, no see, aga! I missed your presence around here!

Easy enough to draw. But there is no guarantee that such an arrangement would be stable. And if it was, no guarantee that it would be planar. I can see the O-O-Cr triangles rotating 90°.

Edit
That is what chemsketch does with it anyway...

Replacing the Cr with a lanthanide in 6+ oxidation state might fare better.

Huh?

Yeah. I dunno what I was thinking really. Well, yes I do, but it fails on all counts.

For a start the highest common oxidation state in the lanthanides is Tb(IV). I forgot that.
Might have better success with an actinide but... well, there are more issues.


I was thinking that a higher coordination number afforded by an f block element would give a couple of electron clouds that might push the oxygen back into a plane. But there are so many problems with that geometry that it failfails.

Let's just call it a spontaneous brain fart and leave it at that.

Maybe some crown ether coordinating a metallic ion, like this one: https://en.wikipedia.org/wiki/Crown_ether#/media/File:18-cro...

1,3,5-trichlorobenzene ?

I just drew it in chemsketch and pressed ctrl-I to get that name - no idea if it does/can exist

You see how the bonds of the oxygenated on the CrO5 create triangles similar to the radiation hazard symbol? That's more of what I'm looking for.

Propellane comes to mind.
But also left and right propeller blade you get from complexing hexacoordinating Metalic core with bidentate ligands...like
Ruthenium (III) Tris-PHEHAT...related to figures 43 in the following link http://www.mdpi.com/1420-3049/19/4/5028/htm

Guanidinium?



Or it's identically-shaped, neutral, theoretical, boron equivalent triaminoborane, a weird molecule
with negative hyperconjugation (B-N bond length increases in order BH2NH2 => BH(NH2)2 => B(NH2)3)

Or the real, isolated B[N(SCF3)2]3

Surely you meant to say, "molecular structure"
