simple energetic materials
I think,
NO2CH2CBrNO2CH3O2N
are a simple powerful energetic material.
Any comments ?

This substance cannot exist. There are several reasons, but I will show you just one.
Every atom (with a few exceptions) requires eight electrons in its outer (valence) shell in order to be stable. Atoms accomplish this by forming
electron bonds. Now, nitrogen has five electrons in its outer shell, which means it needs 3 more electrons to bond to it.
Therefore, it needs three single-pair bonds, conviently abbreviated by a dash.
The nitro group alone has three bonds plus a free bond, but since it's a resonance hybrid, that's allowable. Now, in your chemical, the nitro group
is forced to bond not only to the carbon previous to the bromine (or is it to the bromine? I can't tell), but also to the carbon in the methyl group
to the right. A nitro group with five bonds? No frickin' way. Take some chemistry courses before you start spewing out formulas with nitro groups
all over the place hoping they'll go bang.
The closest chemical I can think of to yours would be trinitrobromopropane, C3H4(NO2)3Br.

I think that was supposed to be O2NCH2CBrNO2CH2NO2 (1,2,3-trinitro-2-bromo-propane), which would exist.
Why the bromine atom? Adding a bromine atom to an organic energetic material would make it less energetic.

It would make it denser and also slightly improve the oxygen balance, and make some nasty fumes upon detonation, but it's not worth the trouble of
getting it there.
And trinitropropane wouldn't be as good as NG from the point of view of power or VoD.

It would improve the density, but I don't think that it's going to make it any more powerful. Think of it this way: mixing TNT with lead is going to
make the TNT denser, but not any more powerful...

Well now that
this has been brought up ...... I have a couple of things I wanted to try.
Methanal + Anhy. Hydrazine = Methanal Hydrazone. (CH2=N-NH2)
Now this is nitrated to replace the one of the H's on the -NH2 to get >
CH2=N-NH-NO2
Also if Chloro Hydrazine (N2H3Cl. prepared from chloro urea) is used instead of just hydrazine to get >
CH2=N-NHCl which if treated with NaN3 would give >
CH2=N-NH-N=N=N
Tetrachloro Hydrazine (N2Cl4) prepared from tetrachloro urea is treated with NaN3 to get an all Nitrogen structure somewhat on the Nitrogen buckyball
principle >
(N3)2-N=N-(N3)2
So theoretically speaking ..... are these possible ?

I must give this material a trial after sleeping.

2,3-dinitrobutane? I don't think it will be particularly powerful; perhaps along the lines of ethylnitrate.

For anyone that`s interested, i have found a description
of a complex energetic material in form of
a tris-cage-compound in my chemistry book
TSTTTPAPNA
C18H42O30N30S3
SHCHCHNNOOHCHNNOOHCHNNOOHCHNNOO
HHNNOOHCHHSHCHCHNNOOHCHNNOOHCHN
NOOHCHNNOOHHNNOOHCHHSHCHCHNNOOH
CHNNOOHCHNNOOHCHNNOOHHNNOOHCHH
In memory of great bio-vesiers of the 19th century.

Tell us how to make it and we might be interested.
Otherwise it's nothing more than a load of letters on a page, is it?

And also you will notice that the title of the topic is "simple energetic materials", which that clearly isn't.

Please correct me if i'm wrong, but I don't think all of the electron shells can hold only 8 electrons( however it is true that nitrogens valence
holds 8), but i believe the first ring holds 2 the second and third hold 8, I think but am not sure that the fourth shell will hold 16.

Well actualy each shell hold only 2, no shells hold 8.

2,3 Dinitrobutane is a powerful explosive in the range of TNT but it displays low thermal stability being a vicinal dinitrocompound!
CH2=O + H2N-NH2 --> CH2=N-NH2 + CH2=N-N=CH2 + 1,3,5-triamino-1,3,5-triazacylohexane
The later cna be obtained by reduction of R-salt (trinitroso brother of RDX) and by reduction of RDX!
There is very little chance the sequence R2N-NH-NO2 can exist!
NH2-NH2 is decomposed by Cl2 and NH2-NHCl isn't isolable intermediary!
N2Cl4 doesn't exist but N2F4 does!
Then maybe that N2F4 + 4NaN3 --> N2(N3)4 + 4NaF
But I doubt it since NF3 and NCl3 are known for age and no mention is done about substitution of the halide by NO, NO2, NH2 or N3!
O2N-CH2-CBr(NO2)-CH2-NO2 is a very powerful explosive power exceeds nitroglycerin and PETN but sensitivity is high and thermal stability low.
There are no scientifical datas that shows a halide slows the down the VOD!
Usually the nitrohalides are sensitive, chemically reactive and therefore unsuitable for military ammos; this explain they haven't been studied
wel; but this doesn't prove them to be less powerful!
I have long searched for the VODs of chloropicirn (trichloronitromethane) and bromopicrin to compare with nitromethane VOD to prove or infirm that
assumption; I also searched for the datas of chloro,bromo or iodo-trinitrobenzene vs TNB and trichloro, tribromo and triiodotrinitrobenzene but found
nothing!
As it is wel known the density of the molecule has a strong effect on the VOD and for related molecules you may say the denser will be more or equaly
powerful!
Triiodotrinitrobenzene>tribromotrinitrobenzene>trichlorotrinitrobenzene >> TNB
And VOD should be in the same order but moisture/chemical stability too!
For halide derivatives the halide contributes to the OB and improves it!
Anyway!
It is logical and proven that:
CH3-NO2 < O2N-CH2-CH2-NO2 < 1,2,3 trinitropropane <...in order of power!
Then you see that:
2(O2N-CH2-)2C(NO2)-Br + Zn/Cu --> (O2N-CH2-)2C(NO2)-C(NO2)(-CH2-NO2)2 + ZnBr2 or CuBr2
Thus the resulting 1,2,3,4 tetranitro-2,3 nitromethyl-butane is a very powerful and dense explosive C6H8(NO2)6
