Praseodymium acetylacetonate
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). It can be prepared by the reaction of trialkoxypraseodymium and acetylacetone. 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. It can form the green complex Pr(acac)3(phen) with o-phenanthroline.
