Erbium ( III) chloride is a chemical compound selected from the group of chlorides.

Production and representation

Erbium ( III) chloride can be obtained by reaction of Erbium (III ) oxide or erbium (III ) carbonate and ammonium chloride.

The hexahydrate is formed by reaction of erbium with hydrochloric acid. By reaction with thionyl chloride it can be converted to the anhydrate.

Erbium (III ) chloride can also be synthesized directly from the elements erbium and chlorine.

Properties

Erbium (III ) chloride is a nearly colorless pinkish red solid. His hexahydrate is a pink -colored hygroscopic solid. Both of which are soluble in water. Erbium ( III) chloride has a monoclinic crystal structure with space group C2 / m corresponding to that of aluminum (III ) chloride. The hexahydrate also has a monoclinic crystal structure with space group P2 / n Erbium ( III) chloride is a good catalyst for the acylation of alcohols and phenols.

Use

Erbium ( III) chloride is used for the preparation of pure erbium. It can also be used as raw material for new kantenverbrückte M6 octahedral cluster compounds as CsErTa6Cl18 be performed for the electron and stability studies.
