Alkalides properties

Tsai, K.-L. and Dye, J.L., Synthesis, properties, and characterization of nanometer-size metal particles by homogeneous reduction with alkalides and electrides in aprotic solvents, Chem. Mater., 5, 540,1993. 

In this overview of alkalides and electrides, the methodologies and special techniques used will be briefly described, and the structural features and electronic, optical and magnetic properties wiU be summarized. The reference lisl is far from complete, but the information given can provide many additional references to the original literature in this field. 

Many properties of alkalide crystals, powders, and films were measured. The original alkalide, Na (C222)Na , has been most thoroughly studied, in part because of the high stability of pure samples. In contrast to most alkalides, single crystals and vapor-deposited films of this sodide are stable in vacuo for many hours, even at room temperature. In addition to the crystal structure, we measured the thermodynamics of formation by an EMF method, optical... 

Alkali- (and alkaline-earth) metal solutions of liquid ammonia display some bizarre properties that can be accounted for in terms of solvated electrons. The solvated electron is an excellent one-electron reducing agent and can be used to produce peroxides, superoxides, and metals with negative oxidation states. Compounds involving crown ethers and cryptands of the alkali metals in ammonia and related solvents yield the very rare electrides and alkalides.
