Lanthanum acetylacetonate
# Lanthanum acetylacetonate

Lanthanum acetylacetonate is a coordination compound with the chemical formula $La(C_5H_7O_2)_3,$ 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). It can be prepared by the reaction of lanthanum alkoxide and acetylacetone. Its tetrahydrate decomposes into monohydrate at 110 °C, obtains the anhydrous form at 150 °C, undergoes $La(CH_3COO)(acac)_2$ and $La(CH_3COO)_2(acac),$ and at 180~285 °C lanthanum acetate is produced. It can be used to prepare $NaLaS_2,$ $La_2Zr_2O_7$ and other materials.
