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]
