Synthesis and Characterization of the Molybdenum Carbonyl‐Functionalized Zintl Ions [(η4‐Pb4)Mo(CO)3]4− and [Pb4{Mo(CO)3}3]6−

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The reaction of the tetrahedral [Pb4]4− with Mo(CO)4(tmeda) yields two different Mo(CO)3‐functionalized clusters which can both be related to known clusters by the same substitution pattern following the isolobal principle. The crystal structures of [Na([2.2.2]crypt)]2Na2[(η4‐Pb4)Mo(CO)3] · 8.7NH3 and Na6[Pb4{Mo(CO)3}3] · 22NH3 are reported.

Reorientations in plastic crystal phases of zintl alloys [PDF]

Physica A: Statistical Mechanics and its Applications, 1993
Abstract Quasielastic neutron scattering measurements on the Zintl alloy NaSn show that the high-temperature solid phase discovered by Hume-Rothery is a plastic crystal characterized by rapid rotations of the Sn {4-} 4 Zintl ions. The reorientations are similar to those previously observed in CsPb but have a markedly different wave vector ...

On the Phase Width of MgZn2/KHg2‐Type Intermetallics AIIMg2−xZnx (A = Ca, Sr, Ba) and the New Compounds (Sr/Ba)11Mg16Zn6 and Ba6Mg2.8Zn8.2

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The continuous, but obviously geometrically limited Mg↔Zn substitution in members of the two basic structures types of intermetallics, the KHg2‐type dizincides, and the MgZn2/Laves‐type dimagnesidesof Ca, Sr, and Ba exhibit a large phase widths for CaMg2 only. Instead, the larger alkaline‐earth elements form the “optimized” complex compounds A11Mg16Zn6

Organotitanyl “TiCp” Fragment Capping the Bowl‐Shaped Unit in the Ternary Anion [(Cp)Ti(Sn3Bi3)]2−

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 12, 3 August 2026.
A novel ternary anion, [(η5‐Cp)Ti(Sn3Bi3‐κ3)]2− composed of a cyclopentadienyl titanium fragment coordinated by a Sn3Bi3 bowl‐shaped cluster unit, is reproted. Unlike homoatomic nine‐atom clusters of heavier tetrel elements, which retain their identity upon dissolution, intermetalloid clusters are not formed directly from ternary alkali‐metal alloys in

Stacking Fault Complexions in AgSbTe2 Thermoelectrics With Enhanced Electrical Conductivity

Advanced Functional Materials, Volume 36, Issue 65, 13 August 2026.
Atomic‐scale characterization resolves stacking fault complexion in AgSbTe2, showing Te and Sb segregation along with lattice dilation. Their enhanced effects on phonon scattering are modeled analytically. Although most defects also impede electron transport, local four‐point‐probe measurements reveal higher electrical conductivity at stacking fault ...

Coupled Operando Mössbauer‐Raman Spectroscopic Analysis of Iron Molybdate Catalysts During Oxidative Dehydrogenation

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
We demonstrate the potential of a coupled SMS‐Raman setup for the ODH of EtOH over a Fe2(MoO4)3 + MoO3 catalyst during reductive conditions. Coupling both methods allows to distinguish (sub)surface and bulk properties of the material during catalysis, that can be correlated with activity and selectivity data from mass spectrometry.

Hydrogenation Properties of LnAl₂ (Ln = La, Eu, Yb), LaGa₂, LaSi₂ and the Crystal Structure of LaGa₂H_0.71(2)

Crystals, 2019
Many Zintl phases take up hydrogen and form hydrides. Hydrogen atoms occupy interstitial sites formed by alkali or alkaline earth metals and/or bind covalently to the polyanions.

Intergrowth Domains of Various Coloration Types in Metastable Li2.76Sn—A Phase Occurring in Tin Anodes of Lithium‐Ion Batteries

Small Structures, Volume 7, Issue 8, August 2026.
Operation of ion batteries typically requires multistep processes within both electrodes, often studied via operando or in situ techniques. However, the obtained results are not always straightforward to interpret; transient phases cannot always be isolated. This article analyzes formation, composition, structure, and thermal behavior of the metastable

Capture the missing: formation of (PbBi3)− and {[AuPb5Bi3]2}4− via atom exchange or reorganization of the pseudo‐tetrahedral Zintl anion (Pb2Bi2)2−

Natural Sciences, 2022
(Pseudo‐)tetrahedral p‐block atom units have been attracting the interest of many scientists, mainly regarding their use as elegant starting materials for compounds with larger molecular or extended architectures.
