Praseodymium(III) acetate is an

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

${\displaystyle {\mathsf {6CH_{3}COOH+Pr_{2}O_{3}\ \xrightarrow {T} \ 2Pr(CH_{3}COO)_{3}+3H_{2}O}}}$

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

${\displaystyle {\mathsf {6CH_{3}COOH+Pr_{2}(CO_{3})_{3}\ \xrightarrow {T} \ 2Pr(CH_{3}COO)_{3}+3H_{2}O+3CO_{2}}}}$↑

${\displaystyle {\mathsf {6CH_{3}COOH+2Pr(OH)_{3}\ \xrightarrow {T} \ 2Pr(CH_{3}COO)_{3}+6H_{2}O}}}$

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]
