Tris(ethylenediamine)nickel perchlorate is a coordination complex with ethylenediamine to nickel ions. It is easy to prepare and is highly energetic, deflagarating easily in a flame.

Properties

Chemical

Tris(ethylenediamine)nickel perchlorate is highly explosive, though its oxygen balance is not optimal, with excess ethylenediamine in the structure. Although it is energetic, it can be stored indefinitely. It is poorly soluble in water, and this can be used to aid in its production.

Physical

Unlike its nickel perchlorate precursor, tris(ethylenediamine)nickel perchlorate has a strongly purple hue.

Preparation

Tris(ethylenediamine)nickel perchlorate can be prepared by dissolving nickel(II) oxide, hydroxide, or carbonate in perchloric acid and then adding ethylenediamine until the solution turns purple. After a day it will precipitate and the crystals can be collected.

Safety

Keep away from open flames.
