Terbium(III) perchlorate

Chemical compound From Wikipedia, the free encyclopedia

Terbium(III) perchlorate refers to an inorganic compound having chemical formula Tb(ClO4)3(H2O)x. Usually this salt is encountered as its hexahydrate. 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.[6][7]
