Spotlight on Alkali Metals: The Structural Chemistry of Alkali Metal Thallides
Crystals, 2020 Alkali metal thallides go back to the investigative works of Eduard Zintl about base metals in negative oxidation states. In 1932, he described the crystal structure of NaTl as the first representative for this class of compounds.
