Chemical crystallography and crystal engineering [PDF]

open access: yesIUCrJ, 2014
Today, there is very little doubt that chemistry owes as much to crystallography as crystallography does to chemistry. This mutual synergy defines modern chemical crystallography.

Why is interoperability between the two fields of chemical crystallography and protein crystallography so difficult? [PDF]

open access: yesIUCrJ, 2019
The interoperability of chemical and biological crystallographic data is a key challenge to research and its application to pharmaceutical design. Research attempting to combine data from the two disciplines, small-molecule or chemical crystallography ...

Twinning in chemical crystallography – a practical guide

open access: yesZeitschrift Fur Kristallographie - Crystalline Materials, 2016
Abstract A non-negliglible percentage of crystal structures in chemical crystallography are derived from twinned crystals. The treatment of these data is dependent on the type of twinning. Twins by strict, pseudo or reticular merohedry may hamper space group determination and structure solution, while non-merohedral twins mainly hinder ...

New opportunities in biological and chemical crystallography

open access: yesJournal of Synchrotron Radiation, 2001
Banerjee [Proc. R. Soc. (1933), 141, 188-193] offered a new way of approaching the crystallographic phase problem which not only broke new ground beyond the 'trial and error' structure solution method of that time but also heralded the extremely powerful direct methods of crystallography of the modern era from the 1970s onwards in chemical ...

Chemical Crystallography [PDF]

open access: yesNature, 1890
IN contradistinction to works on systematic and physical crystallography, this little volume is devoted to crystallography in its far more fascinating relations to chemical constitution.

Radiation damage in chemical crystallography [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Although crystals suffering radiation damage is a well-known and studied phenomena for macromolecular crystallography[1], as far as we are aware there appears to be no such published work relating to chemical crystallography. However, there are numerous anecdotal accounts of disintegrating crystals and resolution progressively dropping off that have ...

Automated chemical crystallography. [PDF]

open access: yesJournal of the American Chemical Society, 2010
The first fully automated small-molecule robotic X-ray diffractometer is described. After demonstrating the utility of the instrument using multiple samples of ammonium bitartrate, we investigated the conformational chirality of diphenyl dichalcogenide (E(2)Ph(2), where E = S, Se, or Te).

Chemical Crystallography at the Advanced Light Source

open access: yesCrystals, 2017
Chemical crystallography at synchrotrons was pioneered at the Daresbury SRS station 9.8. The chemical crystallography beamlines at the Advanced Light Source seek to follow that example, with orders of magnitude more flux than a lab source, and various in
