Stabilization and chemical bonding in Zintl phases

Journal of Physics C: Solid State Physics, 1973
The factors affecting the formation of B32 Zintl phases are examined. Evidence is presented that the pseudopotential effects discussed by others have not been shown to be essential, and that the structures must still be accounted for largely by geometric factors.

Anionic superstructures in liquid Zintl phases

Plasmas & Ions, 2000
Abstract In many liquid alloys of the alkali metals with members of the post-transition sp elements intermediate-range ordering occurs. It is supposed that in such alloys, which have an ionic character, the anions form clusters (polyanions). These clusters are remnants of the so-called Zintl ions, found in many of the corresponding solid alloys ...

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).

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

Isolated, Complex Zintl Molecules in the Gas Phase

Angewandte Chemie International Edition in English, 1988
Ternary and quaternary intermetallic molecules such as Cs2InSb3 and CsSnBiSb2, respectively, can be detected in the vapor above the corresponding alloys by mass spectrometry. The composition of the compounds is in agreement with the Zintl‐Klemm‐Busmann concept, if one assumes that the alkali metal transfers an appropriate number of electrons to the ...

Synthesis and revised structure of the Zintl phase Li7Ge12

Solid State Sciences, 2011
Abstract The structure of the binary Zintl phase Li7Ge12 has been revised. A good-yield synthesis of Li7Ge12 has been elaborated by the reaction of the elements in stoichiometric amounts using an arc melter. Subsequent annealing led to a single-phase product, and single crystals suitable for an X-ray structure determination were obtained using a high-

Trigonal SrAl2H2: the first Zintl phase hydride

Journal of Alloys and Compounds, 2000
Abstract The title compound and its deuteride were synthesized by hydrogenating/deuterating SrAl 2 at 50 bar H 2 /D 2 pressure and temperatures below 200°C. As found by in situ X-ray powder diffraction, the hydrogenation of SrAl 2 proceeds in three steps, with SrAl 2 H 2 as the first product.

Bonding properties of the new zintl‐phase hydrides

International Journal of Quantum Chemistry, 2004
AbstractWe investigated the electronic structure of three recently discovered Zintl‐phase hydrides: SrAl2H2, Ca3SnH2, and Ca5Sn3H. The energy bands and the total and partial densities of states were computed by means of the full‐potential linearized augmented‐plane‐wave method. We found the SrAl2H2and Ca5Sn3H hydrides are metallic and Ca3SnH2is a small‐
