Rare earth perchlorates can be prepared by the reaction of rare earth oxides and perchloric acid, usually containing crystal water, and its molecular formula is RE(ClO4)3·nH2O, n=2.5, 3, 4, 5, 6, 7, 8, 9. The amount of bound water is related to the type of element. When n=9, the relevant rare earth perchlorate is Sm(ClO4)3•9H2O and Sm(ClO4)3•9H2O; when n=8, the rare earth perchlorate The salt is La(ClO4)3•8H2O, Ce(ClO4)3•8H2O, Pr(ClO4)3•8H2O, Nd(ClO4)3•8H2O, Y(ClO4)3•8H2O; when n=6, the rare earth The chlorates are Tb(ClO4)3•6H2O and Er(ClO4)3•6H2O. Rare earth perchlorates are widely used in the field of biological research because the chlorate ions contained therein can form functional complexes with various ligands.

The structure of rare earth perchlorate is RE(ClO4)3·nH2O, n=2.5, 3, 4, 5, 6, 7, 8, 9. The coordination polyhedron of rare earth ions is octahedron, among which RE(ClO4)3·6H2O is a cubic crystal system and belongs to the Fm3m space group. Its central ion coordination number is 6, 6 oxygens come from water, and perchlorate does not participate in coordination.
