Gadolinium oxalate is the oxalate of gadolinium, with the chemical formula Gd2(C2O4)3. Its hydrate can be prepared by the reaction of gadolinium nitrate and oxalic acid.[1]

Properties

The decahydrate of gadolinium oxalate thermally decomposes to obtain the anhydrous form, which can then be heated to produce gadolinium oxide.[2] Gadolinium oxalate reacts with hydrochloric acid to produce Gd(C2O4)Cl.[3] It also reacts with sodium hydroxide under hydrothermal conditions to produce gadolinium hydroxide.[1]
