Thulium(III) acetate explained

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.^[1]

Properties

Thulium(III) acetate reacts with iron acetylacetonate at 300 °C, which can form the hexagonal crystal TmFeO₃.^[2]

Reacting thulium(III) acetate with trifluoroacetic acid will produce thulium trifluoroacetate:^[3]

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