Interstitial‐Electron‐Induced Topological Molecular Crystals

Advanced Physics Research, 2023
Topological phases are usually unreachable in molecular solids, which are characterized by weakly dispersed energy bands with a large gap, in contrast to topological materials. In this work, however, it is proposed that nontrivial electronic topology may

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.

Thermoelectric properties and electronic structure of the Zintl phase Sr5Al2Sb6 [PDF]

Dalton Transactions, 2014
The Zintl phase Sr5Al2Sb6 has a large, complex unit cell and is composed of relatively earth-abundant and non-toxic elements, making it an attractive candidate for thermoelectric applications. The structure of Sr5Al2Sb6 is characterized by infinite oscillating chains of AlSb4 tetrahedra.

Revealing the Nature of Chemical Bonding in an ALn₂Ag₃Te₅-Type Alkaline-Metal (A) Lanthanide (Ln) Silver Telluride

Inorganics, 2019
Although the electronic structures of several tellurides have been recognized by applying the Zintl-Klemm concept, there are also tellurides whose electronic structures cannot be understood by applications of the aforementioned idea.

Bonding Schemes for Polar Intermetallics through Molecular Orbital Models: Ca-Supported Pt–Pt Bonds in Ca10Pt7Si3

Crystals, 2013
Exploratory synthesis in the area of polar intermetallics has yielded a rich variety of structures that offer clues into the transition in bonding between Zintl and Hume-Rothery phases. In this article, we present a bonding analysis of one such compound,

Prediction of topological Dirac semimetal in Ca-based Zintl layered compounds CaM2X2 (M = Zn or Cd; X = N, P, As, Sb, or Bi)

Scientific Reports, 2022
Topological Dirac materials are attracting a lot of attention because they offer exotic physical phenomena. An exhaustive search coupled with first-principles calculations was implemented to investigate 10 Zintl compounds with a chemical formula of ...

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).
