X-Ray Crystallography

X-ray crystallography determines the atomic and molecular structures of crystalline solids by analyzing the diffraction patterns of X-rays interacting with crystal lattices. This method gives three-dimensional electron density maps that reveal atomic positions, chemical bonds, and crystallographic features, making it indispensable across chemistry ...

2-[(E)-2-(4-Ethoxyphenyl)ethenyl]-1-methylquinolinium 4-fluorobenzenesulfonate

Acta Crystallographica Section E, 2014
In the structure of the title salt, C20H20NO+·C6H4FO3S−, the 4-(ethoxyphenyl)ethenyl unit is disordered over two positions with a refined site-occupancy ratio of 0.610 (6):0.390 (6). The cation is nearly planar, the dihedral angle between the quinolinium

1-(2,4-Dinitrophenyl)-2-[(E)-(3,4,5-trimethoxybenzylidene)]hydrazine

Acta Crystallographica Section E, 2014
Molecules of the title compound, C16H16N4O7, are not planar with a dihedral angle of 5.50 (11)° between the substituted benzene rings. The two meta-methoxy groups of the 3,4,5-trimethoxybenzene moiety lie in the plane of the attached ring [Cmethyl–O–C–C ...

From Strain to Pressure: Atomically Resolved Mechanisms of Stress Dissipation in Emissive, Elastically Deformable Molecular Crystals Under Ambient and High Pressure

Advanced Optical Materials, EarlyView.
Molecular crystals must withstand both isotropic and anisotropic stress to function in flexible optoelectronics and high‐pressure devices. In situ high‐pressure single‐crystal X‐ray diffraction coupled with DFT‐D computations reveal how an emissive molecular crystal with interdigitated packing bends elastically at ambient‐pressure and remains ...

De Novo Design and Directed Evolution Refinement of Mirror‐Image Protein Binders Targeting Interleukin‐4

Advanced Science, EarlyView.
This study presents the de novo design and directed evolution of a mirror‐image D‐protein inhibitor targeting human interleukin‐4 (IL‐4). The engineered molecule exhibits nanomolar binding affinity for IL‐4 and effectively inhibits IL‐4–mediated signaling.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

(E)-1-(2,4-Dinitrophenyl)-2-(3-ethoxy-4-hydroxybenzylidene)hydrazine

Acta Crystallographica Section E, 2014
The molecule of the title hydrazine derivative, C15H14N4O6, is essentially planar, the dihedral angle between the substituted benzene rings being 2.25 (9)°. The ethoxy and hydroxy groups are almost coplanar with their bound benzene ring [r.m.s. deviation
