In Situ Hydrogenation of the Zintl Phase SrGe
Inorganic Chemistry, 2017 Hydrides (deuterides) of the CrB-type Zintl phases AeTt (Ae = alkaline earth; Tt = tetrel) show interesting bonding properties with novel polyanions. In SrGeD4/3-x (γ phase), three zigzag chains of Ge atoms are condensed and terminated by covalently bound D atoms.

The new Zintl phases Eu21Cd4Sb18 and Eu21Mn4Sb18 [PDF]
Journal of Solid State Chemistry, 2016 Abstract Crystals of two new Zintl compounds, Eu21Mn4Sb18 and Eu21Cd4Sb18 have been synthesized using the molten metal flux method, and their structures have been established by single-crystal X-ray diffraction. Both compounds are isotypic and crystallize in the monoclinic space group C2/m (No. 12, Z=4).

Novel metastable metallic and semiconducting germaniums [PDF]
, 2012 By means of ab initio metadynamics runs we explored the lower-pressure region of the phase diagram of germanium. A monoclinic germanium phase with four-membered rings, less dense than diamond and compressible into \beta-tin phase (tI4) was found.

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.
