I just synthesised tetramine zinc permanganate through the reaction of KMnO4 with a solution of liquid ammonia and ZnO and ammonium chloride. It is
unusable - it decomposes into manganese dioxide with the moisture in the air.
Does anyone know whether aluminium oxide would react in the same way (see reactivity series,) because copper is too stable to react and I am worried
about the sensitivity of tetramine magnesium permanganate if it formed at all.
Any ideas?

Just a wild guess...
"A nitrogen rich explosive" could it/you be "octanitrocubane"?
Zn(NH3)4(MnO4)2 from KMnO4, NH4OH, ZnO and NH4Cl...weird...
--> How are you sure it is what you think it is?
The combination of NH3 or NH4 with MnO4 accounts for the unstability (N2, NO2(-), NxOy, NO3(-) formation from NH3).
From your claim the complex will decompose upon contact with air moisture...
--> so you immediately decompsed it because ab initio, you have a lot of water from NH4OH (75% at least) so your product is ruined while
crystalizing (assuming the complex is soluble) or while precipitating...
I would start from Zn(NO3)2, NH4NO3 and NH4OH since NH4Cl is bad news with KMnO4...releases Cl2.
Or from moist Zn(MnO4)2 and passing NH3 gas onto it.
Your second part of the text doesn't make sense!
1°) Al2O3 will not react the same way...NH4OH or NH3 doesn't complexate Al(3+).
2°) Cu is not too stable to react... Cu2O or CuO may eventually form a complex with NH4OH or NH3 and maybe afterwards Cu(NH3)4(MnO4)2
3°) I dont think Mg will form a tetraamino complex...nor a complex at all. You may have more chance with Ca.

between both compounds. Anyway, it is sensitive material. Detonation is usually weak, with weakly sound and weak (nothing) mechanics effect on
aluminium 0,1 mm surface plate. At amount 0,1g of Cu x C2. ...LL...
P.S. : During next a lot attempts is clearly, that Philou has truth in every in word. From TACN liquid, arises CuC2, with very weak properties for
deminers using.

Cu2C2 is also unstable upon storage at least if moist for too long it turns into Cu2C and Cu or CuO/Cu2O...
To maximise the yield of Cu2C2, one has to start from CuCl (white) dissolved in NH4OH.
White CuCl can be obtained easily from CuCl2 by boiling it with chunks of native Cu or Cu powder...the dark green emerald solution turns then dark
brown- kaki...
You simply have to add cold distillated water to the dark brown solution and it will get much clearer and you will get snow white crystals
precipitation. Collect fast, and transfer into cold conc NH4OH solution, dissolve it by swirling.
Once done bubble acetylen through this last solution and you should get a precipitate of Cu2C2--> filtrate, dry as much as possible with paper
dowel, then dry in a cold vented/aerated place and use fast...beware of its sensitivity.

Thanks Philou, it are next important informations. Starting material is CuCl. Not CuCl2. Simply and interesting methode for conversion CuCl2 on CuCl.
Maybe tried it......LL
