Chemical compound

Thulium(III) acetate is the acetate salt of thulium, with the chemical formula of Tm(CH3COO)3. It can exist in the tetrahydrate or the anhydrous form.[2]

## Properties

[edit]

Thulium(III) acetate reacts with iron acetylacetonate at 300 °C, which can form the hexagonal crystal TmFeO3.[3]

Reacting thulium(III) acetate with trifluoroacetic acid will produce thulium trifluoroacetate:[4]

Tm(CH3COO)3 \+ 3 CF3COOH → Tm(CF3COO)3 \+ 3 CH3COOH
