Short Sb···Sb Contacts in Polymorphic Tris(p‐Tolyl)Antimony: A Hallmark of Organoantimony(III) Solid‐State Chemistry?

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Discovery of polymorphism in solid tris(p‐tolyl)antimony(III) highlighted short, direct antimony‐antimony contacts, with interatomic separation shorter than the sum of the van der Waals radii, and calculated interaction energy of ca. 26 kJ mol−1 that includes a significant dispersion component.

Analysis of lattice changes and weak interactions in a series of solvatomorphic isostructural spin‐crossover compounds

open access: yesActa Crystallographica Section C, EarlyView.
Five new solvatomorphic spin‐crossover compounds were crystallized and structurally characterized. Variable‐temperature X‐ray diffraction, Hirshfeld surface analysis and NCI plots shed light on the role of weak interactions.Five new solvate forms of the complex bis(thiocyanato‐κN)[tris(pyridin‐2‐ylmethyl)amine‐κ4N,N′,N′′,N′′′]iron(II), [Fe(NCS)2 ...

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Analysis of cation‐π interactions using quantum chemistry and statistical analysis of high‐resolution protein structures

open access: yesThe FEBS Journal, EarlyView.
Shown is a typical detail of a high‐resolution crystal structure (PDB ID 1B5E, chain A) showing the nearness of a phenylalanine residue, Phe24, and a lysine residue, Lys32, that are not engaged in the proposed cation–π interaction. The study statistically examines charged residues near phenylalanine's aromatic ring, supported by quantum chemical ...

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

open access: yesChemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...

3-Benzyloxybenzaldehyde: Ab initio powder structure determination and Hirshfeld surface analysis

open access: yes, 2013
The crystal structure of 3-benzyloxybenzyldehyde (2) has been determined from laboratory X-ray powder diffraction data. The DFT optimized molecular geometry in 2 agrees closely with that obtained from the X-ray study.

Crystal structure and Hirshfeld surface analysis of 1-[6-bromo-2-(4-fluorophenyl)-1,2,3,4-tetrahydroquinolin-4-yl]pyrrolidin-2-one

open access: yes
In the title compound, C19H18BrFN2O, the pyrrolidine ring adopts an envelope conformation. In the crystal, molecules are linked by intermolecular N - H...O, C - H...O, C - H...F and C - H...Br hydrogen bonds, forming a three-dimensional network.
