Crystallography books

Different indices are used in hexagonal cells (we build a c.p.h. crystal up by adding bricks in four directions, not three as in cubic). We do not need them here - the crystallography books listed under Further Reading at the end of this chapter do them more than justice. 

The theory of diffraction can be found in any crystallography book. The so-called structure factor F(h,k,l), where h, k, and / are the Miller indexes for the diffraction spots, is the Fourier transformation of the electron densities inside... 

Perhaps the last general overview of crystallography in all its many aspects, including crystal chemistry and crystal physics and the history of crystallographic concepts, as well as the basics of crystal structure determination, was a famous book... 

A special notation is used to describe surface reconstructions and surface overlayers and is described in books on surface crystallography (Clarke, 1985). The lattice vectors a and b of an overlayer are described in terms of the substrate lattice vectors a and b. If the lengths la I = mlal and Ib l = nibl, the overlayer is described as mXn. Thus, a commensurate layer in register with the underlying atoms is described as 1 X 1. The notation gives the dimension of the two-dimensional unit cell in terms of the dimensions of an ideally truncated surface unit cell. 

This book contains a selection of chapter topics based on papers given at the 12th conference of the Commission on Charge, Spin and Momentum Density of the International Union for Crystallography, held in Waskiesiu, Prince Albert National Park, SK, Canada, July 27-August 1, 1997. The choice of topics represents some of the latest advances in the field of electron, spin, and momemtum densities and the analysis of these densities with respect to their roles in determining chemical reactivity. 

For work with the method of x-ray diffraction two items were necessary to study the theory and to learn to work with x-rays. So Mark studied together with Weissenberg Niggli s book on crystallography thoroughly. To work with soft x-rays, as it is necessary for diffraction work, was rather difficult at those times. X-Ray tubes for these purposes were not available com-... 

A number of points are relevant for a full crystallochemical characterization for each of them a few noteworthy remarks will be presented in the following. To this end, crystallographic conventions, nomenclature and symbols will be used. For a summary of these and of the corresponding definitions the most important reference book is International Tables for Crystallography (Hahn 2002). 

This hst of books is by no means considered an exhaustive list on protein X-ray crystallography. These are merely books that I have found useful, or have been recommended to me by colleagues. Other suggestions for additions to this hst will be gratefully received.

Transmission electron microscopy (TEM) can provide detailed stmcture of zeolites. I use the word characterize or characterization for stmctural study on a unit cell scale, such as various kind of stmctural defects and basic stmctural units, and determine or determination for obtaining atomic coordinates within the unit cell for all the atoms of a crystal. A simple text or reviews for stmctural characterization of porous materials can be found in a book or review articles [1-6]. Now, we are in a new era, that is, we can determine new stmctures of micro- and mesoporous materials only by electron microscopy(EM), an area called electron crystallography (EC) [7-11]. 

Several examples of carbenoid ion-radicals are discussed within this book. A silylene anion-radical preparation and properties is exemplified here. Scheme 2.5 shows the path to this species. Tetrakis(di-tert-butytmethylsilyl)disilylene was reduced by lithium or sodium salt of naphthalene anion-radical in THF at 78°C and then 12-crown-4 was added to the resulting reaction mixture. The silylene anion-radical was obtained as the corresponding alkali salt. Red crystals of the salt were isolated and characterized by ESR spectroscopy and x-ray crystallography (Inoue et al. 2007). 

This book tells the story of the ubiquitin system as we currently know it from the regulation of basic cellular processes to quality control and the pathogenetic mechanisms of disease, from X-ray crystallography of the 26S proteasome to the interaction between substrates and their ligases, to the development of mechanism-based drugs, and to target-specific aberrant processes.

Chemical crystallography is the study of the principles of chemistry behind crystals and their use in deseribing strueture-property relations in solids. The prineiples that govern the assembly of crystal and glass structures are deseribed, models of many of the teehnologically important erystal struetures are studied, and the effect of crystal structure on the various fundamental meehanisms responsible for many physical properties are discussed. This new book presents and reviews data on the coordination chemistry of several metal complexes with dipicolinic acid and the erystal structure of some antimalarial metal complexes. 

Low temperature crystallography is a discipline deeply entangled with the techniques of X-ray diffraction on cooled samples and very often cryo-crystallog-raphy and low temperature dijfraction are used as synonymous. This reflects a more general problem of crystallography, a science often considered just at the level of a technique, a confusion that hopefully this book will contribute to remove.
