Synthesis of Neodymium(III) acetylacetonate

1.25 g of neodymium(III) nitrate hexahydrate in 7 mL of aq. 95% ethanol is placed in a reflux apparatus, whereto 1 mL of acetylacetone is added and the solution is brought to a gentle reflux for 30 minutes. The solution is combined with 1.5 g of sodium acetate trihydrate dissolved in 8 mL of water and it is heated to 70°C for 20 minutes. The mixture is placed in a refrigerator until cold, filtered and washed with a little cold water. The product is obtained as a hydrate and it is left to dry in open air.

3 C5H8O+ Nd(NO3)3 · 3H2O = Nd(C5H7O2)· xH2O + 3 HNO3

C5H7NaO2 + HNO3 = NaNO3 + C5H8O2
