Thulium(III) oxalate is the oxalate of thulium with the chemical formula Tm2(C2O4)3. Its hydrate can be prepared by reacting an aqueous solution of thulium(III) chloride and a benzene solution of dimethyl oxalate.[2] Its pentahydrate is decomposed by heat to obtain the dihydrate, which is further heated to obtain thulium(III) oxide.[3] It reacts with hydrochloric acid to obtain H[Tm(C2O4)2]·6H2O.[4]
