Praseodymium(III) acetate is an inorganic salt composed of a Praseodymium atom trication and three acetate groups as anions. This compound commonly forms the dihydrate, Pr(O2C2H3)3·2H2O.[2]

Preparation

Praseodymium(III) acetate can be formed by the reaction of acetic acid and praseodymium(III) oxide:[3]

Praseodymium(III) carbonate and praseodymium(III) hydroxide can also be used:

Decomposition

When the dihydrate is heated, it decomposes to the anhydrous, which then decomposes into praseodymium(III) oxyacetate(PrO(O2C2H3)) then to praseodymium(III) oxycarbonate, and at last to praseodymium(III) oxide.[2]
