Terbium(III) acetate is the acetate salt of terbium, with a chemical formula of Tb(CH3COO)3.

Physical properties

Terbium(III) acetate reacts with caesium carbonate to form a precipitation of terbium hydroxycarbonate, which reacts with excess caesium carbonate and dissolves again. The reaction was irradiated with ultraviolet light with a wavelength of 365 nm, which has the characteristic green light of terbium.

The tetrahydrate of terbium acetate can lose hydration at 60 °C, obtaining the anhydrate at 180 °C, which starts to decompose at 220 °C, forming terbium oxide at 650 °C.[1]
