Reduction of polycyclic aromatic hydrocarbons by sodium in the presence of the chelating ether diglyme in THF resulted in the formation of radical carbanion salts. The crystal structure of a Na(diglyme)2pyrenide, a new member in this material class, was solved from single-crystal X-ray diffraction data. The green compound crystallizes in the monoclinic space group P21/c with unit cell parameters of a=8.9908(4) Å, b=16.6367(8) Å, c=19.1723(7) Å, β=94.734(2)°, V=2857.9(2) Å3, and Z=4 (T=20 °C).

二甘醇二甲醚钠阳离子络合物稳定的多环芳烃自由基阴离子



在 THF 中存在螯合醚二甘醇二甲醚的情况下,用钠还原多环芳烃,导致自由基碳负离子盐的形成。 Na(二甘醇二甲醚) 2 芘化物(此类材料中的新成员)的晶体结构是通过单晶 X 射线衍射数据解析出来的。绿色化合物在单斜空间群 P2 1 /c 中结晶,晶胞参数为 a=8.9908(4) Å, b=16.6367(8) Å, c=19.1723(7) Å, β= 94.734(2)°,V=2857.9(2) Å 3 ,Z=4(T=20°C)。
