Lanthanum acetate explained

Lanthanum acetate is an inorganic compound, a salt of lanthanum with acetic acid with the chemical formula . 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:

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

Physical properties

Lanthanum(III) acetate forms colorless crystals.

Lanthanum acetate dissolves in water.

Lanthanum acetate forms hydrates of the composition, 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.
