Praseodymium acetylacetonate is a coordination compound with the chemical formula Pr(C₅H₇O₂)₃, or Pr(acac)₃ for short. Its instability constants (logY_n) are 2.89, 4.17 and 5.29 (corresponding to n=1, 2, 3).[1] It can be prepared by the reaction of trialkoxypraseodymium and acetylacetone.[2] When praseodymium chloride reacts with sodium acetylacetonate or lithium acetylacetonate in the solid phase, praseodymium acetylacetonate can also be obtained, but NaPr(acac)₄ or LiPr(acac)₄ will also be generated.[3] It can form the green complex Pr(acac)₃(phen) with o-phenanthroline.[4]
