1. green bullets
2. green fuel
3. gay sensitivity training for US Marines in the field
4. green explosives

Ummm......I see a pattern.

I finally thought there probably were other nickel hydrazine complexes, and I found this.

Novel Polynuclear Nickel(II) Complex: Hydrazine, Sulfato, and Hydroxo Bridging in an Unusual Metal Hexamer. Crystal Structure and Magnetic Properties of [Ni₆(N₂H₄)₆(SO₄)₄(OH)₂(H₂O)₈](SO₄)(H₂O)₁₀

The sulfate anion, that's the yellow sulphur atom bound to four red oxygen atoms, has a charge of minus two. The perchlorate anion has a charge of minus one. So my guess is that there are twice as many perchlorate anions in nickel hydrazine perchlorate that use an oxygen to oxygen bond, like you find in hydrogen peroxide, bonding adjacent perchlorate anions, IMHO, so that the net charge of the molecule is zero. (The pale green Ni atoms are nickel. The dark blue N atoms are nitrogen. The unmarked dark atoms bound to nitrogen are hydrogen.)

What Is A Coordination Compound?

Hydrazine gives the best performance as a rocket fuel, but it has a high freezing point and is too unstable for use as a coolant.

Perchlorates can be very strong oxidizing agents, e.g. The mixture of a perchlorate and any organic material may result in explosion that may be touched off by friction...

Have you ever used small-arms ammunition equipped with lead-free primers?

I have.

From a shooting perspective, they went "bang" every time, hit the target, and showed the same muzzle velocity for bullet weight as similar lead styphnate primed ammunition.

From a reloader's perspective ... looks like I don't have to tumble the brass. It comes out of the weapon already clean.

I was really worried about that. There was a news story online about how the Russians have built an even more powerful version of the US’ MOAB, and tried to sell it as green technology by pointing out that it doesn’t generate nuclear fallout.

It also isn’t very powerful compared with a nuke, of course. And it’s not as if they’ve scrapped their nuclear arsenal.

Thanks neverdem.
