Tetrazole based energetic oxidizers
In a report just published few month ago
A list of oxygen positive - tetrazole based compounds's theoretical calculations and studies are published.
If these compounds are stable, they are likely going to revolutionize new high energy dense oxidizers. Just 3 compound of most interest from this
paper.
Sadly, synthesis or sensitivilty calculations are not published on this report.
To read the report easier, here are all the compounds in the big list so you dont need to keep on going up and down to check.

And finally here is the report.

Also, if someone can help me find some info about this compound, I would also like to know how the di-tetrazine rings are formed. any paper, detail,
info would be grateful.

Compound 51
Compound 51
Density 1.94
Molar mass : 265.0987
Mp:113 (dec 135)
OB : +9.1%
VoD : 9000
IS : 9J
FS :?
hof: +123.4
It seems a good replacement for AP, it also less sensitive to shock than RDX, ADN. The synthesis is also not too complicated.

Although compound 51 has interesting properties as HEDM such as high crystal density and VoD, but the synthesize is not necessarily easy. You forget
that you must synthesize compound 49 first. Moreover the overall yield (44%) for 51 is not good. As explosive, compound 51 is similar in performance
to HMX, Pcj of 51 is 393 kbar if we calculated from Pcj=ρD2/4. However the decomposition of HMX is higher generally over 200 °C ( see, LLNL
Explosives Handbook-Properties of Chemical Explosives and explosive simulants (rev.2-1985), section 6-42) from the Differential Thermal Analysis (the
decomposition of HMX is accelerated after melting.

Yes, it is outperformed by the cheaper hmx in vod and it has a lower 350 kbar. however It looks good for an oxidizer, I would say the synthesis is not
more difficult than ADN. Its sensitivity is fairly low, I will synthesis a small quantity of this early next year when I get a new lab.
here I found are some more oxygen-positive tetrazole compounds.
some most interesting one in the paper are -
Compound D and E (C2 H N9 O10) has OB + 20.1%
Compound J (C3 H2 N12 O12) is also incredibly oxygen positive with OB + 20.1%
K seems most sensitive, and G and H are also oxygen positive and seems stable. I will try using the forumulas for calculating stability, from the
papers you sent me, they dont seem very complicated. Thank you btw.
here is the paper

From the above compound 51.

A similar compound compound, which its synthesis is in the uploads, and its shape in the above link, I think can be further nitrated into 3,5
Di-Tri-Nitromethyl-1,2,4Triazole
Although the 1,2,3 triazole version of the above compound exist.. Look at the price !
