Electron crystallography: imaging and single-crystal diffraction from powders.
The study of crystals at atomic level by electrons - electron crystallography - is an important complement to X-ray crystallography. There are two main advantages of structure determinations by electron crystallography compared to X-ray diffraction: (i) crystals millions of times smaller than those needed for X-ray diffraction can be studied and (ii) the phases of the crystallographic structure...
متن کاملRedetermination of the crystal structure of β-zinc molybdate from single-crystal X-ray diffraction data
The crystal structure of the β-polymorph of ZnMoO4 was re-determined on the basis of single-crystal X-ray diffraction data. In comparison with previous powder X-ray diffraction studies [Katikaneani & Arunachalam (2005 ▸). Eur. J. Inorg. Chem. pp. 3080-3087; Cavalcante et al. (2013 ▸). Polyhedron, 54, 13-25], all atoms were refined with anisotropic displacement parameters, leading to a higher pr...
متن کاملX-ray single crystal and powder diffraction: possibilities and applications
In this article the main possibilities of single crystal and powder diffraction analysis using conventional laboratory x-ray sources are introduced. Several examples of applications with different solid samples and in different fields of applications are shown illustrating the multidisciplinary capabilities of both techniques. Handbook of instrumental techniques from CCiTUB X-ray single crystal...
متن کاملBiliary cholesterol crystallization characterized by single-crystal cryogenic electron diffraction.
Cholesterol crystals are the building blocks of cholesterol gallstones. The exact structure of early-forming crystals is still controversial. We combined cryogenic-temperature transmission electron microscopy with cryogenic-temperature electron diffraction to sequentially study crystal development and structure in nucleating model and native gallbladder biles. The growth and long-term stability...
متن کاملSingle - crystal neutron diffraction study of b - Cs 3 ( HSO
The structure of -Cs3(HSO4)2[H2ÿx(SxP1ÿx)O4] has been examined by single-crystal neutron diffraction at 15 K. The compound crystallizes in space group C2/c and contains four formula units in the unit cell, with lattice parameters a = 19.769 (9), b = 7.685 (2), c = 8.858 (3) AÊ and = 100.60 (4) . Re®nement of P, S and H site occupancies indicated that the value of x (in the stoichiometry) is 0.5...
