Dysprosium acetate is an inorganic compound with the formula Dy(CH₃COO)₃.^[3] It forms hydrates including a tetrahydrate.^[4]

Preparation

Dysprosium acetate can be obtained by treating dysprosium oxide with acetic acid:^[1]

Dy₂O₃ + 6 CH₃COOH → 2 Dy(CH₃COO)₃ + 3 H₂O

Its hydrate, when heated to 150 °C in vacuum, yields the anhydrous triacetate.^[5]

Reactions

Dysprosium(III) acetate tetrahydrate catalyzes the cyclization of 2-{[2-(phenylsulfonyl)hydrazinylidene]methyl}benzoic acid (BSHOPA) to form 2-(phenylsulfonyl)phthalazin-1(2H)-one (PSP).^[6]

Dysprosium(III) acetate forms a variety of coordination polymers, e.g. with cymantrenecarboxylic acid.^[7]
