Structure and Morphology of Indole Analogue Crystals [PDF]
ACS Omega, 2020 Indole and six simple analogues were crystallized in different environments to study the crystal habit changes. All crystal structures were determined by X-ray diffraction experiments. Lattice energies based on DFT-D3 periodic calculations and framework analysis were used to define the most important intermolecular interactions in the crystal ...

Growth and morphology of C60 crystals [PDF]
Chemical Physics Letters, 1992 Abstract Single crystals of pure C 60 are grown from the vapour phase. The crystal morphology is compared to the theoretical equilibrium form, predicted on the basis of a periodic bond chain analysis and a statistical mechanical approach. Some interesting growth phenomena are observed and discussed.

Two-Dimensional Hydrogen-Bonded Crystal Structure, Hirshfeld Surface Analysis and Morphology Prediction of a New Polymorph of 1H-Nicotineamidium Chloride Salt [PDF]
, 2019 A new polymorph of 1H-nicotineamidium chloride salt, (C6H7N2O)+·Cl−, was grown by slow evaporation at room temperature. It crystallizes in the monoclinic space group P21/m. The crystal structure study shows that the organic cations (C6H7N2O)+

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
