On Oxalyl Halide Isothiocyanates Part I: Syntheses and Isomerism

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 21, 25 July 2026.
Oxalyl halide isothiocyanates can be prepared from oxalyl halide with one equivalent of NH4SCN in liquid SO2. While oxalyl bromide isothiocyanate can be isolated as a liquid, the respective chloride compound readily undergoes isomerization under formation of a thiazole ring, which is obtained as a solid.

Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 21, 25 July 2026.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...

Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 28, 25 July 2026.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.

Crystal structure and Hirshfeld surface analysis of dimethyl(phenyl)phosphine sulfide

open access: yesActa Crystallographica Section E Crystallographic Communications
The title compound, C8H11PS, which melts below room temperature, was crystallized at low temperature. The P—S bond length is 1.9623 (5) Å and the major contributors to the Hirshfeld surface are H...H (58.1%), S...H/H...S (13.4%) and C...H/H...C contacts (11.7%).

Stabilizing the Hexacyanotrimethylenecyclopropane Electron Acceptor—Structural and Photophysical Characterization

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 30, 20 July 2026.
An improved low‐temperature synthesis enables the first comprehensive structural and spectroscopic characterisation of neutral hexacyanotrimethylenecyclopropane (CN6CP). Combined IR/Raman, UV–Vis and ssNMR analyses reveal a deeper understanding of its oxidation‐state‐dependent charge redistribution, σ‐aromaticity of the cyclopropane core, and redox ...

“Innocent” Electrolytes Can Influence Organic Electrosynthetic Selectivity

open access: yesChemElectroChem, Volume 13, Issue 14, 17 July 2026.
Organic electrosynthesis has emerged as a powerful strategy for leveraging inexpensive and abundant electricity in organic synthesis, but understanding the role of inert supporting electrolyte is largely unexplored. This article investigates cobalt‐based metal–carbon bond homolysis and elucidates how supporting electrolytes influence reaction rates ...

Crystal structure and Hirshfeld surface of a pentaaminecopper(II) complex with urea and chloride

open access: yesActa Crystallographica Section E Crystallographic Communications
The reaction of copper(II) oxalate and hexamethylenetetramine in a deep eutectic solvent made of urea and choline chloride produced crystals of pentaaminecopper(II) dichloride–urea (1/1), [Cu(NH3)5]Cl2·CO(NH2)2, which was characterized by single-crystal X-ray diffraction.
