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

Production and representation

Thulium (III ) chloride can be obtained by reaction of thulium (III ) oxide, or thulium (III ) carbonate and ammonium chloride are obtained.

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

Thulium (III ) chloride can also be synthesized directly from the elements thulium and chlorine.

Properties

Thulium (III ) chloride is a pale yellow powder. His hexahydrate is a light green hygroscopic solid. Both of which are soluble in water. Thulium (III ) chloride has a monoclinic crystal structure with space group C2 / m corresponding to that of aluminum (III ) chloride.
