Lanthanum acetylacetonate is a coordination compound with the chemical formula La(C₅H₇O₂)₃, or abbreviated as La(acac)₃. Its instability constants (logY_n) are 3.65, 5.13 and 6.12 (corresponding to n=1, 2, 3).[2] It can be prepared by the reaction of lanthanum alkoxide and acetylacetone.[3] Its tetrahydrate decomposes into monohydrate at 110 °C, obtains the anhydrous form at 150 °C, undergoes La(CH₃COO)(acac)₂ and La(CH₃COO)₂(acac), and at 180~285 °C lanthanum acetate is produced.[4] It can be used to prepare NaLaS₂, La₂Zr₂O₇ and other materials.[5][6]
