Neodymium(III) oxalate

Neodymium(III) oxalate is the oxalate salt of neodymium, with the chemical formula of Nd₂(C₂O₄)₃ in the anhydrous or hydrate form. Its decahydrate decomposes to the anhydrous form when heated, and when heated further, decomposes to Nd₂O₂C₂O₄,^[2] finally obtaining neodymium(III) oxide.^[3] It dissolves in hydrochloric acid to form Nd(C₂O₄)Cl·3H₂O.^[4]
