编辑同志: 《化学通报》1982年11期“化学简讯”栏发表了一篇短文“以负离子形式存在的钠”。按这个报道,似乎Na~-离子是新近合成的。这与实际情况不符。 J.L.Dye等于1973年已由金属钠溶于二环聚醚二胺(以C表示)的乙胺溶液(或四氢呋喃溶液)合成得到NaC~+Na~-晶体化合物。浓NaC~+Na~-乙胺溶液冷却析出金色结晶,具有金属光泽,但该晶体挤压成形的
Editor’s Comrade: “Chemistry Bulletin” 1982-11 “Chemistry Bulletin” column published an essay “in the form of negative ions of sodium.” According to this report, it seems that Na ~ - ions are newly synthesized. This does not match the actual situation. J. L. Dye et al., 1973 have synthesized NaC ~ + Na ~ - crystals from sodium ethylamine solution (or tetrahydrofuran solution) of sodium metal dissolved in a bicyclic polyetherdiamine (denoted C). Concentrated NaC ~ + Na ~ - ethylamine solution precipitated golden crystals, with a metallic luster, but the crystal extrusion
