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.
Preparation Praseodymium(III) acetate can be formed by the reaction of acetic acid and praseodymium(III) oxide at elevated temperatures:
Structure According to X-ray crystallography, anhydrous praseodymium acetate is a coordination polymer. Each Pr(III) center is nine-coordinate, with two bidentate acetate ligands and the remaining sites occupied by oxygens provided by bridging acetate ligands. The lanthanum and holmium compounds are isostructural.
Decomposition When the dihydrate is heated, it decomposes to the anhydrous form, which then decomposes into praseodymium(III) oxyacetate () then to praseodymium(III) oxycarbonate, and at last to praseodymium(III) oxide.
