Observation of gas phase anionic bismuth Zintl ions

Journal of the American Chemical Society, 1989
The authors report in this communication the first observation of gas-phase anionic Zintl ions of bismuth. Laser-ionization time-of-flight mass spectra of mixed bismuth/alkali clusters produced by a gas aggregation source were investigated in their laboratory and found to exhibit maxima for clusters corresponding to reported Zintl ions.

Synthesis and characterization of ternary Zintl phases

2018
Two new compounds were found in the K-Si-As system. One of them, K[subscript]2SiAs[subscript]2, is isostructural with K[subscript]2SiP[subscript]2 with infinite [subscript]sp[infinity]1 (SiAs[subscript]2) [superscript]-2 chains, while KSi[subscript]3As[subscript]3 adopts a new structure type with infinite puckered [subscript]sp[infinity]2 (Si[subscript]

Li21Si5, a Zintl phase as well as a Hume-Rothery phase

Journal of Solid State Chemistry, 1987
Li21Si5 is the most lithium-rich phase in the binaryLiSi system and substitutes the so-called Li22Si5. This was proved by a careful X-ray structure analysis (F4¯3m-T2d; a = 1871.0pm; Z = 16; R = 0.052; 397hkl). The reduced Li content is due to ordered vacancies in the huge 6 × 6 × 6 superstructure of bcc (cF416).

Search for new Zintl phases for thermoelectricity

2017
In order to find promising candidates for materials with a high thermoelectric (TE) figure of merit, various Zintl phases were designed or chosen from literature and synthesised by melting elements together. These included Yb2SnGe2, Yb2InGe2, Sr2PbGe2, Sm4Bi2Te, Yb4Sb2S and SmGa6Te10.

Probing the Zintl–Klemm Concept: A Combined Experimental and Theoretical Charge Density Study of the Zintl Phase CaSi

Angewandte Chemie International Edition, 2014
AbstractThe nature of the chemical bonds in CaSi, a textbook example of a Zintl phase, was investigated for the first time by means of a combined experimental and theoretical charge density analysis to test the validity of the Zintl–Klemm concept. The presence of covalent SiSi interactions, which were shown by QTAIM analysis, supports this fundamental

Electronic structure of intermetallic B32 type Zintl phases

2005
The electronic properties of binary and ternary intermetallic Zintl phases crystallizing in the NaTl type of structure are investigated and reported. The crystal and defect structure, the electronic band structure and density of states, the bonding mechanisms and the charge transfer are discussed. Comparison is made between the electronic states in the
