Dysprosium acetylacetonate is a chemical compound of dysprosium with formula Dy(C₅H₇O₂)₃(H₂O)_n.

Preparation and properties

Dysprosium acetylacetonate can be prepared by reacting dysprosium or dysprosium hydride with acetylacetone. Dy(acac)₃·EtOH·0.5Hacac (where Hacac represents acetylacetone) can be obtained by electrolysis of dysprosium cathode in ethanol solution of acetylacetone, which can be heated to generate Dy(acac)₃ through Dy(acac)₃·EtOH. It is a colorless solid. Its anhydrous form is stable in dry atmosphere and it forms a hydrate in humid air. It can form Dy(acac)₃·2CH₃OH and Dy(acac)₃·CH₃OH·CH₃CN in a methanol solution of acetonitrile.

Applications

Dysprosium acetylacetonate can be used to catalyze the addition reaction of norbornene and carbon tetrachloride. The dihydrate has been characterized by X-ray crystallography.
