Sodide ion

Compounds containing the sodide ion (Na ) have recently been made ... 

The first of these was the sodide ion, Na, formed from the reaction of sodium with the cryptand N (C2H40)2C2H4)3N in the presence of ethylamine ... 

Among the intriguing developments in alkalide chemistry has been the recent synthesis of inverse sodium hydride, which contains a sodide ion, Na, and an ion encapsulated in 3 adamanzane. The H" in this structure is strongly coordinated by four nitrogen atoms in the adamanzane ligand, shown in Figure 8-8(b). 

The spectra of the sodide ion and the potasside ion at low temperatures show relatively sharp line widths, indicative of low ion-solvent interactions suggesting that these ions in solution resemble those... 

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... 

The per-aza cryptand TriPip222 (Figure 8.8c) is able to complex Na ions and is extremely robust towards reduction. In 2005 this cryptand was reported to form Na(TriPip222)]+e, the first electride to be stable at room temperature. Cavities within crystalline [Na(TriPip222)] e accommodate the electrons. The sodide [Na(TriPip222)] Na, with Na trapped in the cavities, was also prepared (Figure 8.8d). ...
