Bis(ethylenediamine)copper(II) perchlorate is an energetic coordination complex of copper(II) made from perchloric acid and ethylenediamine. It is a fluffy purple solid which is nearly black in a concentrated solution. It appears to be indefinitely storable.



Bis(ethylenediamine)copper(II) perchlorate is prone to detonation on light heating.


Crystals of bis(ethylenediamine) copper(II) perchlorate are far from dense - there is a nearly tenfold increase in volume from the starting material, copper(II) oxide.


Bis(ethylenediamine)copper(II) perchlorate is not commerically available but is easy to prepare.


Bis(ethylenediamine)copper(II) perchlorate is prepared through the complexation of a solution of copper(II) perchlorate with ethylenediamine. Since copper(II) perchlorate is not a very commonly encountered chemical, it is often prepared in solution during this synthesis by the addition of an excess of copper(II) oxide to dilute perchloric acid. A detailed preparation can be found here.


Keep away from open flames, as the compound will detonate.
