A ruthenium trichloride hydrate was placed in a separable flask of 5 L in volume so as to contain 80.15 g of ruthenium. To the flask, further 3,500 mL of water and 297.5 g of 2,4-pentanedione were added and refluxed in the air for 2 hours. To the resultant solution, 330 g of sodium acid carbonate was added and refluxed for another 2 hours. From the obtained reaction solution, the organic phase was extracted, vaporized, and dried to obtain 285.3 g of tris(2,4-pentanedionato)ruthenium as a red crystal.
