Crystal Structures and Intermolecular Interactions in α$\alpha$‐ and β$\beta$‐phosgene

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Despite its notorious reputation as a war gas, phosgene (COCl2${\rm COCl}_2$) is one of the most important intermediate chemicals in industry. In this study, we present the crystal structures of two phosgene polymorphs as deduced from powder neutron diffraction and show which intermolecular interactions stabilise the different modifications.

Possible Peierls Distortion Through Re2 Dimer Formation in the LaNiO2‐Type Nitrides LnReN2 (Ln = Pr, Nd)

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
This study presents the high‐pressure synthesis of two new anion‐vacancy‐ordered perovskite‐related nitrides, PrReN2 and NdReN2, featuring distorted LaNiO2‐type structures. X‐ray and neutron diffraction reveal a structural distortion driven by dimerization of Re‐chains, while electronic structure calculations reveal the simultaneous presence of ...

Stepwise Reduction of Ruthenium and Growth of Magnetic Structure During Hydrothermal Crystallisation of SrRu2O6 from KRuO4

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
In situ neutron powder diffraction data collected while heating the Ru(VII) reagent KRuO4 in the presence of aqueous Sr2+ reveal the crystallisation of a Ru(VI) oxyhydroxide before the expected Ru(V) oxide; at the same time evolution of antiferromagnetism in the final SrRu2O6 product follows the growth of its crystal structure.

Water‐Splitting “Without Water”: Splitting of the Crystallised Water of Hydrated Salts

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
Unlike liquid water, the structural and molecular properties of water molecules embedded in hydrated salts are subject to strong influences and vary little. This makes them potential candidates for the water splitting reaction. Here, we present the first example of the electrochemical decomposition of crystallised water.
