Synthesis of Tb(TMHD)3

To a beaker add 5.52 g of dipivaloylmethane dissolved in 7.5 mL of methanol and 1.62 g of sodium reacted with 7.5 mL of methanol. Then dropwise 4.53 g of terbium nitrate hexahydrate dissolved in 10 mL of hot methanol is added to the solution with stirring. Then with stirring the mixture is poured to 100 mL of cold water and stirred for 10 minutes. Filter, wash with some water and recrystallize in hot acetonitrile.
