Properties
Chemical
Bis(ethylenediamine)copper(II) perchlorate is prone to detonation on light heating.
Physical
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. It is quite soluble in water.
Explosive
It explodes when exposed to an open flame.
Availability
Bis(ethylenediamine)copper(II) perchlorate is not commerically available but is easy to prepare.
Preparation
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.
