Lanthanum acetate is an inorganic compound, a salt of lanthanum with acetic acid with the chemical formula La(CH
3CO

3. According to X-ray crystallography, anhydrous lanthanum acetate is a coordination polymer. Each La(III) center is nine-coordinate, with two bidentate acetate ligands and the remaining sites occupied by oxygens provided by bridging acetate ligands. The praseodymium and holmium compounds are isostructural.[1]

## Synthesis

Lanthanum acetate can be formed by the reaction of lanthanum(III) oxide and acetic anhydride:

3 \+ 3(CH
3CO)
2O → 2La(CH
3COO)

It is also made in a reaction of lanthanum oxide with 50% acetic acid:

3 \+ 6CH
3COOH → 2La(CH
3COO)
3 \+ 3H

## Physical properties

Lanthanum(III) acetate forms colorless crystals.

Lanthanum acetate dissolves in water.

Lanthanum acetate forms hydrates of the composition La(CH
3COO)
3•nH
2O, where n = 1 and 1.5.[2][3]

Lanthanum acetate and its hydrates decompose when heated.

## Uses

Lanthanum acetate is used in specialty glass manufacturing and in water treatment.

Also, it is used to produce porous lanthanum oxyfluoride (LaOF) films.[4]

It is also used as a component in the production of ceramic products and as a catalyst in the pharmaceutical industry.
