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.

NaCdSb: An Orthorhombic Zintl Phase with Exceptional Intrinsic Thermoelectric Performance

Angewandte Chemie International Edition, 2022
AbstractMany Zintl phases are promising thermoelectric materials owning to their features like narrow band gaps, multiband behaviors, ideal charge transport tunnels, and loosely bound cations. Herein we show a new Zintl phase NaCdSb with exceptional intrinsic thermoelectric performance.

Zintl Phases: Transitions between Metallic and Ionic Bonding

Angewandte Chemie International Edition in English, 1973
AbstractExperimental studies on compounds of alkali and alkaline earth metals with semi‐ and metametals have considerably broadened the basis for a discussion of the transition from metallic to ionic bonding. Current interest is focused mainly upon the elucidation of the principles governing the structure of such compounds which are subject to a wide ...

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 ...

Hydrogenous Zintl Phases: Interstitial Versus Polyanionic Hydrides

2010
Hydrogen may be incorporated in Zintl phases in two different ways: either hydridic where H is exclusively coordinated by electropositive metals (interstitial hydrides), or as part of the polyanion ...

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‐

Mercury and cadmium pnictidehalides: the inverted Zintl phases

Russian Chemical Bulletin, 2001
The structures of the mercury and cadmium pnictidehalides MaZbXc (M = Cd, Hg; Z = P, As, Sb; X = Cl, Br, I) are discussed on the basis of the Zintl--Klemm concept. Primary attention is paid to the relationship between the crystal and electronic structures of the compounds in question.

Elastic Properties of the Layered Zintl-Phase CaSi2

physica status solidi (a), 2001
The elastic properties of CaSi 2 are studied by X-ray analysis of strained silicide films grown by reactive deposition epitaxy on Si(111). The diffraction linewidths are found to be mainly determined by heterogeneous strain with negligible size broadening. Homogeneous strain is induced by lattice mismatch for epitaxial films thinner than 50 nm, and is

Ternary Antimonide EuSn3Sb4 and Related Metallic Zintl Phases

Journal of Solid State Chemistry, 2000
Abstract The ternary Zintl compound europium tin antimonide, EuSn3Sb4, has been synthesized at 900°C in the presence of a tin flux, and its structure has been determined by single-crystal X-ray diffraction methods. It crystallizes in the orthorhombic space group D162h-Pnma with a=9.954(2), b=4.3516(7), c=22.650(4) A, and Z=4 at 22°C.

Magnetic hyperfine interactions in the Zintl phase EuZnSn

Journal of Materials Chemistry, 1997
Magnetic susceptibility, 119 Sn and 151 Eu Mossbauer effect measurements are reported for the Zintl phase EuZnSn which crystallizes with the TiNiSi-type structure. The stannide shows Curie–Weiss behaviour above 40 K with an experimental magnetic moment of µ exp =7.88(5) µ B /Eu, close to that of the free Eu 2+ ion of µ eff
