Bismuth‐Rich Intermetallic Rods with a Note of Zintl‐Phase

Zeitschrift für anorganische und allgemeine Chemie, 2023
AbstractBlack needle‐shaped crystals of the bismuth‐rich mixed halogenide Bi21Rh4Cl6I7were obtained by slow cooling of a melt of Bi, RhI3and BiCl3. Single‐crystal X‐ray diffraction revealed an orthorhombic structure that consists of infinite intermetallic rodsBi9Rh2]3+and discrete anionic groups [BiII2Cl2I5]3−and [BiIIICl4I2]3−.

Superconductivity in layered Zintl phase LiSn2As2

, 2021
We report the superconductivity in the layered Zintl phase LiSn$_2$As$_2$, which is isostructural to NaSn$_2$As$_2$ and has a transition temperature ($T_{\mathrm{c}}$) of 1.6 K. Despite similar $T_{\mathrm{c}}$ and Debye temperatures, substituting of Na with Li considerably increases the upper critical field. Based on a systematically comparation of Sn$

Single‐Atom Control of Aromaticity and Excited‐State Dynamics in Endohedral Zirconium–Antimony Zintl Clusters

Angewandte Chemie, EarlyView.
Single‐atom growth from [Zr@Sb12]2− to [Zr@Sb13]3− disrupts the closed‐shell S2P6 superatomic configuration and markedly attenuates three‐dimensional (3D) aromaticity. Ultrafast spectroscopy further links stronger spherical aromaticity to slower excited‐state relaxation, establishing an atom‐resolved structure‐aromaticity‐dynamics relationship ...

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.
