Terbium(III) chloride (TbCl3) is a chemical compound. In the solid state TbCl3 has the YCl3 layer structure.[2] Terbium(III) chloride frequently forms a hexahydrate.
Preparation
The hexahydrate of terbium(III) chloride can be obtained by the reaction of terbium(III) oxide and hydrochloric acid:[3]
- Tb2O3 + 6 HCl → 2 TbCl3 + 3 H2O
It can also be obtained by direct reaction of the elements:[4]
- 2 Tb + 3 Cl2 → 2 TbCl3
Properties
Terbium(III) chloride is a white,
orthorhombic plutonium(III) bromide crystal structure with space group Cmcm (No. 63).[6][7] It can form a complex Tb(gly)3Cl3·3H2O with glycine.[8]
Applications
Terbium(III) chloride is used in the
solid-state devices.[10]
Hazards
Terbium(III) chloride causes
Conditions/substances to avoid are: heat, acids and acid fumes.References
