| Section2= }} Hexadecacarbonylhexarhodium is a metal carbonyl cluster with the formula Rh6(CO)16. It exists as black crystals that are soluble in organic solvents. ==Discovery and synthesis== Rh6(CO)16 was first prepared by Heiber in 1943 by carbonylation of RhCl3·3H2O at 80-230 °C and 200 atm carbon monoxide with silver or copper as a halide acceptor. It was incorrectly formulated as Rh4(CO)11. Subsequently, the carbonylation of a mixture of anhydrous rhodium trichloride and iron pentacarbonyl was shown to give good yields of Rh6(CO)16. Other compounds of rhodium are also effective precursors such as Rh2Cl2(CO)4 and rhodium(II) acetate: :3 Rh2(O2CCH3)4 + 22 CO + 6 H2O → Rh6(CO)16 + 6 CO2 + 12 CH3CO2H :3 Rh2Cl2(CO)4 + 4 CO + 6 Cu → Rh6(CO)16 + 6 CuCl 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Hexadecacarbonylhexarhodium」の詳細全文を読む スポンサード リンク
