Hi,
I see several vendors (in China) are offering this compound. But has anyone else tried to draw it? Since the Hg is in it's +2 oxidation state, the only structure I can produce is long, long chains (maybe toruses)?

Certainly it's EASY to see how a monobasic salt is formed.


But given that the Sb-O-Sb bond has an angle of 109 degrees (or so), it can't be a monomer, I don't think. Hg 2+ forms linear compounds so it would have to bind to 2 pyroantmonate groups.
 
What's it used for? Is it toxic like organomercurics?
 
No - I've found https://patents.google.com/patent/RU95103039A/en which is from 1995.

There was a lot or rubbish in 1985 about 'Red Mercury' and it's uses. I am simply wondering what is going on here? I wondered if the title material:

1)Allows energy to be stored as Wigner energy with a much higher energy density (so a form of energy storage)
2)IF it's composed of long chain (macromolecular) crystals and, if a certain temperature it will decompose to much less dense antimony oxides https://en.wikipedia.org/wiki/Antimony_oxide and mercury oxide.

If both are true, this is a material that might be able to exert an enormous pressure. It ticks all the boxes of the various Red Mercury theories.

Will it produce the 25 million degrees to set of a fusion reaction? I doubt it, I REALLY doubt it.... but I think the Russians may have tried it.

Just, you know, a vague interest.

Oh, and if a friendly physicist reads this - just how hot and how much pressure could it produce? It might be a more compact alternative to conventional explosives thus making those scary 'suitcase nukes' possible.... I doubt it.

It may well be toxic, but more along the lines of an inorganic mercury/inorganic antimony salt. The oxides are usually insoluble in water so they don't pose a special toxicity risk - but obviously I don't know about Mercury (II) pyroantimonate, not many people seem to.

I suppose, ultimately, the Russians are/were trying to develop a ballotechnic. The US (including Sandia) have also researched this https://en.wikipedia.org/wiki/Ballotechnics

Of course, if Mercury (II) pyroantimonate can store (for several months) and release a huge amount of Wigner energy, they hoped to reach the temperatures and pressures needed to start off fusion. I'm guessing that the Hg is being displaced.
 
MgSO2H3o2- is my go-to for, for example: cyclohexanone, H2O2, phenethylacetaldehyde and ammoniac. It yields 4-HO-Piperidine-Phenethyldehyde
