Synthesis and Characterization of Bimetallic Zintl Clusters and their Use in the Fabrication of Intermetallic Nanoparticles
… characterization and applications of bimetallic Zintl clusters are explored. Zintl ions are polyanions of main group elements, primarily of the heavier elements of groups 14 and 15. The closo-Sn<sub>9</sub>Ir(cod)<super>3-</super>, Sn<sub>9</sub>Rh(cod)<super>3-</super>, and …

Advancing Nontoxic, Antimony-based 1–2–2-type Thermoelectric Zintls
… advances of nontoxic, antimony-based 1–2–2-type Zintl thermoelectric materials from three aspects. Firstly, p-type CaMg2Sb2 has not been favorably considered a promising thermoelectric material in comparison to other Zintl phases. However, a series of meticulously designed tactics is successfully …

Polar intermetallic compounds of the silicon and arsenic family elements and their ternary hydrides and fluorides
… of trivalent metals. A new series of isomorphous Zintl compounds with the Ca16Sb11-type structure were prepared and studied as well.;All the alkaline-earth-metal tetrelides, A5Tt3, that crystallize in the Cr5B3-type structure can be interstitially derivatized by hydrogen or fluoride. Stannides and …

Advancing the computational exploration for thermoelectric materials
… Compounds such as Mg3Sb2 and the A1B2C2 Zintl thermoelectrics belong to class of layered materials which are more tightly bound than vdW layered materials, due to the existence of an ionically-bound “spacer” elements between the layers. Using a modified version of the slab-cutting …
