某些教科书对[Co(NH_3)_6]~(3+)及[Co(NH_3)_6]~(2+)等配离子的颜色说法不一。本文作者合成了有关的两种钴氨配合物,进行了红外和X射线结构鉴定,绘制了其水溶液的吸收曲线,证明[Co(NH_3)_6]~(3+)为土黄色,而非如许多教科书上所记述的粉红色.
Some textbooks have different colors for the ion of [Co (NH_3) _6] ~ (3+) and [Co (NH_3) _6] ~ (2+) ions. The authors synthesized two kinds of cobalt-ammonia complexes and identified their structures by IR and X-ray. The absorption curves of their aqueous solutions were plotted, showing that [Co (NH_3) _6] ~ (3+) Many textbooks describe the pink.
