Lanthanum oxalate is an inorganic compound, a salt of lanthanum metal and oxalic acid with the chemical formula La₂(C₂O₄)₃.^[1]^[2]

Synthesis

Reaction of soluble lanthanum nitrate with an excess of oxalic acid:

2 La(NO
3)
3 + 3 (COOH)
2 → La
2(C
2O
4)
3 + 6 HNO
3

Also, a reaction of lanthanum chloride with oxalic acid:

2 LaCl
3 + 3 H
2C
2O
4 → La
2(C
2O
4)
3 + 6 HCl

Physical properties

Lanthanum(III) oxalate forms colorless crystals that are poorly soluble in water.^[3]

The compound forms various crystallohydrates La₂(C₂O₄)₃•nH₂O, where n = 1, 2, 3, 7, and 10.^[4]^[5]

The crystallohydrates decompose when heated.^[6]
