Lanthanum acetylacetonate

Lanthanum acetylacetonate refers to the coordination complex with the formula. This anhydrous acetylacetonate complex has not been characterized well, but the dihydrate has been characterized by X-ray crystallography.
Upon heating under vacuum, the dihydrate converts to the oxo-cluster. This behavior is also observed for erbium, yttrium, gadolinium, and europium.
The instability constants are 3.65, 5.13 and 6.12 have been reported for "La₃". 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 La₂ and La₂, and at 180~285 °C lanthanum acetate is produced. It can be used to prepare NaLaS₂, La₂Zr₂O₇ and other materials.
