[(HN (CH2CH2NH2) 2) 2Ni] (ClO4) 2
Bis-diethylene triamine nickel perchlorate - [(HN (CH2CH2NH2) 2) 2Ni] (ClO4) 2 .
Synthesis:
25 grams. Sodium perchlorate (obtained with a soluble perchlorate)
29 grams. Nickel nitrate hexahydrate
21-22 g diethylenetriamine (DETA)
100 to 200 ml. 95% ethyl alcohol
At the minimum amount of distilled water dissolve nickel nitrate. At the minimum amount of distilled water dissolve perchlorate. Add solution of
nickel nitrate slowly – by drops to DETA
Nickel nitrate solution changed color from green to intense blue in the formation of the complex. The reaction is slightly exothermic. Wait to cool to
room temperature and add solution of perchlorate. Once formed purple - pink colloidal precipitate of [(HN (CH2CH2NH2) 2) 2Ni] (ClO4) 2.
Filtered, washed - once with 2% aqueous solution of DETA, then with ethanol and dry to 40-50*C.
Initiation - Do not succumb to initiate with fire - burns clean hard with compostable. Mixed with 30% sodium perchlorate burns vigorously with intense
flames and popping sound. Heated under confinement detonate.
First test 1 g in a cocktail tube + 0.35 g lead azide - incomplete detonation, some substance was dispersed.
Second test of 22 g approx. density 1.1, may initiate a 1 g pyroxylin + 0.25 g lead azide. Very strong blast with a sharp sound, unpleasant smelling
and white smoke. In strength is similar to CTMTNA or pyroxylin. This energetic substance is less vulnerable, more permanent storage and similar by
power than its analogs [(HN3)6 Ni] (ClO4) 2.

The semicarbazide complex of nickel should also form a perchlorate, perhaps more stable than the hydrazine complex analogue, but sensitivity is
unknown. The hydrazine complex of nickel perchlorate is reportedly dangerously sensitive.

@ Dr Watson,
Do you know that the compound is the bis-complex? Ni tends to prefer 4 four fold square planer co-ordination and such compounds are pink, red, lilac
or orange when nitrogen is involved but two diethylene triamine ligands to one Ni suggests 6-fold coordination. Do you have a reference or did you
just try this as an experiment "on speck".

Nickel complex compounds with NH3, ethylene diamine and others amines formed mainly coordination numbers 6. DETA has three coordinating nitrogen atoms
in the molecule, so the substance should be bis - DETA - nickel perchlorate, but it can be confirmed 100% with crystallographic research fund. I just
decided to share easy and interesting fusion energy substance.

Yes you're right! I have found lots of information about polydentate amine ligands with nickel 2+. While I was looking at this field I came across
fulminato and azido complex of Ni too!

Here is a relevant paper I posted today in the more general thread about energetic complex salts. The paper describes explosive power comparisons for
ethylenediamine and hydrazine complex salts. The tris-hydrazine chromium perchlorate salt appears especially interesting.

I known this study - replacing in that synthesis ethylene diamine with DETA
In a comparative test of [(DETA)2 Ni] (ClO4) 2 with [(EN) 3 Ni] (ClO4) 2 complex with DETA is much more difficult to initiate, but initiation by 1 g
pyroxylin both complex salts are similar in power.
In first "test" of 25 g [(DETA) 2 Ni] (ClO4) 2 in a light plastic housing on wet clay soil is
formed an almost perfect hemispherical crater depth 18cm. and 35 cm. diameter.
In second "test" of 25 g [(EN) 3 Ni] (ClO4) 2 in a light plastic housing on wet clay soil is
forming an irregular oval crater 17 centimeters deep. and a diameter of between 32 and 40 cm.
This is probably due to differences in soil composition, rather than the power of the substances.
