Praseodymium acetylacetonate is a coordination compound with the chemical formula Pr(C5H7O2)3, or Pr(acac)3 for short. Its instability constants (logYn) 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]
