Electron Density

Electron Diffraction and Quantum Crystallography

Focusing on both complex protein structures and small organic molecules, the lecture will explain how adapting electron density models from X‑ray diffraction to electron-based techniques can transform our understanding of molecular interactions and structures on the nanoscale

AI can provide phases at 2 Å: Can Quantum Crystallography help us to a high-quality structure at this resolution?

AI can provide phases at 2 Å: Can Quantum Crystallography help us to a high-quality structure at this resolution?

By exploring the intersection of AI and quantum crystallography, we aim to spark a dialogue on how these fields can co-evolve to tackle the enduring challenges of structural determination in the low-resolution regime.

Electron-density analysis of halide · · · halide through-space magnetic exchange

Electron-density analysis of halide · · · halide through-space magnetic exchange

We present a combined experimental and density functional theory study that characterizes the charge and spin density in NiX2(3,5-lutidine)4 (X = Cl, Br and I). In this material, magnetic exchange interactions occur via Ni2+–halide … halide–Ni2+ pathways, forming one-dimensional chains.

Similarities and Differences in the Electron Density of Cumulated and Conjugated Systems

Similarities and Differences in the Electron Density of Cumulated and Conjugated Systems

QTAIM calculations were conducted to shed light on the nature of bonds in even and odd cumulated systems, with n = 3, 4, 5 and 6, functionalized with alkyls, aryls and N-heterocyclic carbenes (NHCs).
