Establishing electron diffraction in chemical crystallography

Nature Reviews Chemistry, 2021
The emerging field of 3D electron diffraction (3D ED) opens new opportunities for structure determination from sub-micrometre-sized crystals. Although the foundations of this technology emerged earlier, the past decade has seen developments in cryo-electron microscopy and (X-ray) crystallography that particularly enable the widespread use of 3D ED ...

Chemical crystallography of fullerenes

Russian Chemical Reviews, 2004
The state-of-the-art in the structural investigations into fullerene derivatives is surveyed. The crystal structures of individual fullerenes and of their derivatives determined experimentally by single-crystal X-ray diffraction are systematised.

Informatics for chemical crystallography

JOM, 2009
A fundamental question in inorganic crystallography is the relationship between chemical stoichiometry and crystal structure. The relationship between specific compounds and specific crystal structures is usually developed heuristically by surveying crystallographic data of known compounds.

Chemical Crystallography before X‐ray Diffraction

Angewandte Chemie International Edition, 2013
2012/2013 mark the 100th anniversary of von Laue’s diffraction of X-rays from single crystals of copper sulfate, the postulation of Bragg’s law, and the solution of the first X-ray structure. However, even before 1912, the study of crystals was an integral part of chemistry and it played a major role in development of modern chemical science, including

Synchrotron chemical crystallography

Journal of the Chemical Society, Dalton Transactions, 2000
Recent years have seen a considerable development in the availability of single-crystal diffraction facilities with synchrotron radiation for use in non-biological crystallography, with access to several suitable beam-lines around the world. These can markedly extend the range of materials for which a full crystal structure can be determined ...

Chemical crystallography: from inception to maturity

Resonance, 2005
The use of single crystal X-ray diffraction to determine the structure of a chemical compound has been historically classified as ‘Chemical Crystallography’. The methodologies, the accuracy in experiments coupled with the modern computer gadgets and advances in technology makes this branch of science an unequivocal provider of accurate and precise ...

5. Chemical Crystallography

1986
Publisher Summary This chapter discusses chemical crystallography. The chapter begins with a discussion of the reasons for using neutron diffraction for certain problems and a description of the data-collection equipment and procedures at steady-state reactor and pulsed spallation neutron sources.

Structure Correlation Methods in Chemical Crystallography

Crystallography Reviews, 1996
Abstract The structural information collected by X-ray (or neutron) diffraction studies of metallic, ionic, molecular and macromolecular crystals has increased beyond any previously imagined limit. Data are presently compiled in computer-based crystal structure databases.
