Lutetium acetylacetonate is a coordination compound with the chemical formula Lu(C5H7O2)3, or Lu(acac)3 for short. The complex per se is unlikely to exist, but the dihydrate would be expected based on the behavior of other lanthanide tris(acetylacetonate)s. Consistent with this scenario, It forms adducts Lu(acac)3(phen) and Lu(acac)3(dipy) where phen and bipy are 1,10-phenanthroline and 2,2'-bipyridine, respectively. [1]

The complex is somewhat volatile. [2] It can be prepared by the reaction of trialkoxylutetium and acetylacetone. [3]
