|Section2= |Section3= }} Hexamethylbenzene is a white crystalline solid with chemical formula C6(CH3)6. It is an aromatic hydrocarbon with six methyl groups stemming from the carbon centres of the ring. Hexamethylbenzene has historical significance in the field of X-ray crystallography. In 1929, Kathleen Lonsdale first proved the shape of hexamethylbenzene and thus showed that the benzene ring is hexagonal and flat. == Uses == Hexamethylbenzene has no significant commercial uses. The six methyl groups enhance the proton affinity of the central ring. Because it is electron-rich, hexamethylbenzene can be used as a ligand in organometallic chemistry. Two examples from organoruthenium chemistry are the sandwich complexes Ru(ɳ4-C6(CH3)6)(ɳ6-C6(CH3)6) and the dication ()2+. Hexamethylbenzene has been used as a solvent for 3He-NMR spectroscopy. 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「hexamethylbenzene」の詳細全文を読む スポンサード リンク
