Preparation edit

Anhydrous erbium(III) chloride can be produced by the ammonium chloride route.[3][4][5] In the first step, erbium(III) oxide is heated with ammonium chloride to produce the ammonium salt of the pentachloride:

Er2O3 + 10 [NH4]Cl → 2 [NH4]2ErCl5 + 6 H2O + 6 NH3

In the second step, the ammonium chloride salt is converted to the trichloride by heating in a vacuum at 350-400 °C:

[NH4]2ErCl5 → ErCl3 + 2 HCl + 2 NH3

Structural data edit

Erbium(III) chloride forms crystals of the AlCl3 type, with monoclinic crystals and the point group C2/m.[2]

Erbium(III) chloride hexahydrate also forms monoclinic crystals with the point group of P2/n (P2/c) - C42h. In this compound, erbium is octa-coordinated to form [Er(H2O)6Cl2]+ ions with the isolated Cl completing the structure.[6]

Optical properties edit

Erbium(III) chloride solutions show a negative nonlinear absorption effect.[7][clarification needed]

Catalytic properties edit

The use of erbium(III) chloride as a catalyst has been demonstrated in the acylation of alcohols and phenols[8] and in an amine functionalisation of furfural.[9] It is a catalyst for Friedel–Crafts-type reactions, and can be used in place of cerium(III) chloride for Luche reductions.[10]
