Chemical compound

Terbium(III) oxalate is the oxalate of terbium with the chemical formula Tb₂(C₂O₄)₃. Its decahydrate can be obtained by reacting terbium(III) chloride and oxalic acid in an aqueous solution.^[1] Its decahydrate gradually loses water when heated and becomes anhydrous. Continued heating obtains terbium(III,IV) oxide.^[3] It decomposes in isolation from air to form terbium(III) oxide. The decomposed gas products are carbon monoxide and carbon dioxide.^[1] It reacts with hydrochloric acid to obtain H[Tb(C₂O₄)₂]·6H₂O.^[4]
