Terbium perchlorate refers to an inorganic compound having chemical formula Tb(ClO4)3(H2O)x.

This terbium(III) compound can be obtained by treating terbium(III,IV) oxide with perchloric acid.

[4] The perchlorates are non-coordinating anions, so this substance can be used as a starting material for forming Tb(III) complexes.

For example, reaction with alanine forms a complex in which the carboxylate portion of four alanine units bridge between two terbium atoms.

[5] It can be used to synthesize terbium-containing metal-organic framework materials.
