Abstract
Crystalline solids including Zintl anions have been synthesized by an electrolytic process that uses a cathode whose composition is an alloy including the elements forming the Zintl ion and an electrolyte that comprises a solvent that is basic and polar, such as ethylenediamine, and a supporting electrolyte, advantageously organic, that provides a suitable cation for the Zintl anion. Specific examples of solids that have been crystallized include tetraphenylphosphonium gold telluride, tetraphenylphosphonium gallium telluride, and tetrapropylammonium antimony telluride.
