Crystal structures

Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2022
A personal view is offered on various solved and open problems related to crystal structures: the present state of reconstructing the crystal electron density from X-ray diffraction data; characterization of atomic and molecular motion from a combination of atomic displacement parameters and quantum chemical calculations; Bragg diffraction and diffuse ...

Crystal Structure and Prediction

Annual Review of Physical Chemistry, 2015
The notion of structure is central to the subject of chemistry. This review traces the development of the idea of crystal structure since the time when a crystal structure could be determined from a three-dimensional diffraction pattern and assesses the feasibility of computationally predicting an unknown crystal structure of a given molecule.

The crystal structure of triacetylsphingosine

Acta Crystallographica Section B Structural Crystallography and Crystal Chemistry, 1969
The crystal structure of triacetylsphingosine (D-erythro-l,3-diacetoxy-2-acetamido-4-trans-octadecene, C24H43OsN) has been determined by direct methods. The crystals are orthorhombic, P212121, with a = 5.002, b = 8"709 and c = 60.62/~. Positional and isotropic thermal parameters of the non-hydrogen atoms were refined to give a final R index of 0"109 ...

Crystal structure of heliorhodopsin

Nature, 2019
Heliorhodopsins (HeRs) are a family of rhodopsins that was recently discovered using functional metagenomics1. They are widely present in bacteria, archaea, algae and algal viruses2,3. Although HeRs have seven predicted transmembrane helices and an all-trans retinal chromophore as in the type-1 (microbial) rhodopsin, they display less than 15% sequence
