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.

Its anhydrous form is stable in dry atmosphere and it forms a hydrate in humid air.

[5] It can form Dy(acac)3·2CH3OH and Dy(acac)3·CH3OH·CH3CN in a methanol solution of acetonitrile.

[6] Dysprosium acetylacetonate can be used to catalyze the addition reaction of norbornene and carbon tetrachloride.

[7] The dihydrate has been characterized by X-ray crystallography.
