Alkalide ions

However, the situation is somewhat more complicated than Eq. 12.38 would indicate, because the electrons can react further with the metal to form alkalide ions ... 

Aside from the effects of ligand stoichiometry and the nature of the solvent, there are also differences in stability of the alkalide ions. The sodide anion is the most stable, and the ceside ion the leash Because of differential stabilities of the alkalide ions and... 

If alkali metals are dissolved in alkyamines alkalide ions (M") are formed... 

J.L. Dye at Michigan State University discovered that under very special circumstances alkali metals could be coaxed into accepting an electron to form negative ions These ions are called alkalide ions. 

Based on electron affinity values, we would not expect the alkali metals to form anions. A few years ago most chemists would have answered this question with a loud "No" In the early seventies a chemist named J.L. Dye at Michigan State University discovered that under very special circumstances alkali metals could be coaxed into accepting an electron to form negative ions These ions are called alkalide ions.
