Menshutkin Complexes: Influence of Pnictogen, Halide, and Arene on Pn···πarene Interactions in [(PnX3)2{(2‐R‐C6H4)C2H4(2‐R‐C6H4)}]

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 15, October 21, 2025.
A series of complexes consisting of pnictogen(III)‐halides and diphenylethane derivatives have been studied to investigate the influence of the pnictogen atom, the halide, and the substituent R on the organic ligand in terms of Pn···πarene distances and complex type formation, respectively. More than 100 years ago, B. N.

Ice Sheets Without Dynamic Topography

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown.

Bausteine zu einer Oral History der Wissenschaftsgeschichte Auf der Suche: von der Biologie und der Philosophie zur Wissenschaftsgeschichte. Interview mit Soraya de Chadarevian

Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 3, Page 266-289, October 2025.
Wie kann man einen historischen Blick auf das eigene Fach werfen? Diese Frage ist nicht einfach zu beantworten – will man einerseits nicht in einer Nabelschau und Hagiographie enden, andererseits aber auch keinen umfassenden Entwurf einer zukünftigen Historiographie vorlegen.

Two in one: the bismuth bromido clusters in [Bi6Cp*6Br9][Bi7Br24]

Main Group Metal Chemistry, 2014
The reaction of [FeCp*(CO)2]2 in CH2Cl2 with BiBr3 in a 1:1 molar ratio gave the novel bismuth compound [Bi6Cp*6Br9][Bi7Br24] (1), which is composed of a cationic and an anionic bismuth bromido cluster: the cation is based on a hexanuclear bismuth {Bi6 ...

Monitoring the Large Wood Regime in a Partially Regulated Alpine River Following Several Experimental Floods

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract While instream large wood is recognized as vital for healthy river ecosystems, the wood regime remains less understood compared to flow and sediment regimes, primarily due to limited monitoring. Most existing research focuses on unregulated rivers, leaving knowledge gaps in regulated systems.

Role of restraints on hydrogen atoms in Hirshfeld atom refinement: the case of tri‐aspartic acid trihydrate

Acta Crystallographica Section B, Volume 81, Issue 5, Page 484-497, October 2025.
Restraints for atomic displacement parameters of hydrogen atoms in Hirshfeld atom refinement are tested using two polymorphs of the water‐rich l‐Asp‐l‐Asp‐l‐Asp (DDD) crystal structure.Two polymorphs of l‐Asp‐l‐Asp‐l‐Asp (DDD) trihydrate as model compounds for biologically important proton‐shuttle reactions were investigated with the quantum ...

The disilanes Cp*SiCl2SiH3 and Cp*SiH2SiH2Cp*

Main Group Metal Chemistry, 2015
Hydrogenation of Cp*SiCl2SiCl3 (A) (Cp*=C5Me5) with diisobutylaluminum hydride (DIBAL-H) gave partially hydrogenated disilane Cp*SiCl2SiH3 (1) with 45% yield, whereas the reaction with lithium aluminum hydride (LiAlH4) provided the well-known Cp*SiH2SiH3.
