'''Tris(ethylenediamine)nickel perchlorate''' is a coordination complex with [[ethylenediamine]] to [[nickel]] ions. It is easy to prepare and is highly energetic, deflagrating 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.

It dissolves in [[acetone]] and [[methyl ethyl ketone]], and will slowly react with the ketones to form a macrocyclic compound.<ref>D. A. House and N. F. Curtis, Chem. Ind. (London), 42, 1708 (1961)</ref><ref>http://pubs.acs.org/doi/pdf/10.1021/ja00999a008</ref><ref>[https://books.google.ro/books?id=fgXrBwAAQBAJ&pg=PA39&lpg=PA39&dq=Tris%28ethylenediamine%29nickel+perchlorate&source=bl&ots=KMtlNyvJLJ&sig=_iGMBJsPc4UTKXGxpT_4Rifu8Yg&hl=ro&sa=X&ved=0ahUKEwi_j9eFmdfUAhWjdpoKHe3iAMcQ6AEIqAEwEw#v=onepage&q=Tris%28ethylenediamine%29nickel%20perchlorate&f=false Coordination Chemistry of Macrocyclic Compounds, Gordon Melson, p. 39]</ref>

===Physical===
Unlike its [[nickel(II) perchlorate]] precursor, tris(ethylenediamine)nickel perchlorate has a strongly purple hue.

===Explosive===
Tris(ethylenediamine)nickel perchlorate will explode in contact with an open flame.

==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.

==Handling==
===Safety===
Keep away from open flames.

===Storage===
It can be stored in closed containers.

===Disposal===
It can be safely neutralized by detonating it.

Residual perchlorates can be destroyed by adding metallic [[iron]] under UV light, in the absence of air.<ref>[https://books.google.ro/books?id=gjfSBwAAQBAJ&pg=PA106&lpg=PA106&dq=perchlorate+neutralization&source=bl&ots=ztEPz18eE-&sig=oHHZzByFHPVjYIVxbvzGl4SC_xQ&hl=en&sa=X&ved=0ahUKEwi5gpTJm_XJAhVBURoKHb3LB4o4ChDoAQguMAc#v=onepage&q=perchlorate%20neutralization&f=false Perchlorate in the Environment (2000), Edward Todd Urbansky, pag. 106]</ref>
