Melamine itself has solubility issues in water, so a salt would be needed, and I don’t know how prone such a salt would be to hydrolysis. I don’t
have any melamine, but I do have some acetoguanamine, so I might try to mess with that and see if anything promising is yielded.

Thanks for the idea. Ligand replacement is a real breakthrough in the synthesis of metal complexes. It works!
I successfully prepared copper-bis(4-amino-1,2,4-triazole) perchlorate from [Cu(NH3)4](ClO4)2 by reaction:
[Cu(NH3)4](ClO4)2+2ATrz=>[Cu(ATrz)2](ClO4)2+4NH3
[Cu(NH3)4](ClO4)2 was dissolved in hot water, ATrz was added, then the water is depressed with a hair dryer. Dirty blue powder has formed.
I cannot call the [Cu(NH3)4](ClO4)2 a primary explosive. But despite the poor oxygen balance ATrz complex without a shell in an amount of 50-100 mg
burns a very sharp bright flash. I think, placed in the shell is quite suitable.
The substance is not sensitive to friction. 10-20 mg placed in foil burns sharply when heated, but detonates when hit with a hammer on a steel plate.
upd 50mg dried subs detonated without shall!

[Ni(4-aminotriazole)3](ClO4)2 was obtained in the same way. As you said, it does not detonate without a shell, but 30-50 mg in foil detonate when
heated.
How about [Cu(Diaminourea)2](ClO4)2 and [Ni(Diaminourea)3](ClO4)2? Is it stable with long storage? Is it oxidized by oxygen of air? Hydrolysis?
[Cu(aminourea)2](ClO4)2 and [Ni(aminourea)3](ClO4)2?
Is there a way to make [Cu(aminourea)2](ClO4)2 and [Ni(aminourea)3](ClO4)2 from Semicarbazide Hydrochloride?

Carbohydrazide (1,3-diaminourea) can be prepared by amination of Semicarbazide with Hydrazine or just by amination of urea with a large excess of
hydrazine. These amination reactions though, can be complex and will result in aqueous mixtures of Urea, Semicarbazide, Carbohydrazide, and
Hydrazodicarbonamide. If you want a source for Carbohydrazide, pyrohobby.ru might still have some for sale, but they have a horrible payment system
that isn’t secure at all.
trisCarbohydrazide Nickel diPerchlorate (NiCP) apparently works as a decent primary (and is likely stable enough in storage) to function in detonators
as mentioned in some Chinese patents, but at least the trisCHLORATE (NiCC) analogue is also a strong performer; see thread: http://www.sciencemadness.org/talk/viewthread.php?tid=159732
The Cu complex may work as well, though I have no idea and don’t plan to test it. Carbohydrazide is a pain to try to make, at least for me.

Thanks. I understand correctly that carbohydrazide (diaminourea) is more stable than semicarbazide (aminourea)?

Chemically, Semicarbazide is more stable. The hydrazine bond is less stable than the simple amide. But, Carbohydrazide will of course be better as a
fuel, due to the higher energy of the 2 N-N bonds.

It seems strange to me that carbohydrazide is sold in free form, but semicarbazid is sold only in the form of hydrochloride.

Both exist as solids at STP, but Semicarbazide is likely just too hygroscopic and basic, so it’d form hydrated solutions and/or carbonates. Same as
Aminoguanidine and guanidine.
