Thulium(III) oxalateis theoxalateofthuliumwith the chemical formula Tm2(C2O4)3.Its hydrate can be prepared by reacting an aqueous solution ofthulium(III) chlorideand abenzenesolution ofdimethyl oxalate.[2]Its pentahydrate is decomposed by heat to obtain the dihydrate, which is further heated to obtainthulium(III) oxide.[3]It reacts withhydrochloric acidto obtain H[Tm(C2O4)2]·6H2O.[4]
