Copper(II) perchlorate is an inorganic compound with the chemical formula Cu(ClO4)2. It forms hydrates with the formula Cu(ClO4)2(H2O)x. The anhydrous solid is rarely encountered but several hydrates are known. Most important is the perchlorate salt of the copper aquo complex copper(II) perchlorate hexahydrate, [Cu(H2O)6]2+(ClO4)2.[3]

Infrared spectroscopic studies of anhydrous copper(II) perchlorate provided some of the first evidence for the binding of perchlorate anion to a metal ion.[4] The structure of this compound was eventually deduced by X-ray crystallography. Copper resides in a distorted octahedral environment and the perchlorate ligands bridge between the Cu(II) centers.[5]
