X-ray Powder Diffraction Pattern Indexing for Pharmaceutical Applications
Crystal-structure determination using X-ray diffraction from single crystals is a well-developed technique (1). A single crystal structure provides full structural characterization of the form at the atomic scale. The main drawback to single crystal diffraction is the need to grow a sufficiently large and defect-free crystal for analysis, which is not practical for all crystal forms. Furthermor...
متن کاملX-Ray Crystal Structure of [N, N'-bis(4-Methoxysalicylidene) -2, 3-Dimethylaminopropane] Copper(II) Ethanol Solvate
The crystal structure of the title Schiff base complex is obtained by single-crystal X-ray diffraction data.The solid state structure determination reveals that the coordination geometry around the copper(II) center istetrahedrally distorted square-planar. The crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.
متن کاملReconstruction of electron density by the Maximum Entropy Method from X-ray powder diffraction data based on incomplete crystal structure models: a case study of apatites with different intercalated metal atoms
Conventional Fourier analysis is one of the most commonly used methods for localization of missing atoms in crystal structures from powder diffraction data. A “perfect” Fourier map would require a complete set of structure factors up to a resolution of at least sin/ = 5.0 Å. In the case of powder diffraction, accessible information is limited, as compared to single crystal diffraction, mainl...

Evolutionary algorithms are finding increasing use in the study of a wide range of different types of diffraction data. In this chapter, we review recent applications of evolutionary algorithms to study a variety of structural problems. Examples range from the study of disordered materials by analysis of diffuse scattering data to molecular replacement techniques in biological crystallography. ...
متن کاملX-ray and Neutron Diffraction in the Study of Organic Crystalline Hydrates
A review. Diffraction methods are a powerful tool to investigate the crystal structure of organic compounds in general and their hydrates in particular. The laboratory standard technique of single crystal X-ray diffraction gives information about the molecular conformation, packing and hydrogen bonding in the crystal structure, while powder X-ray diffraction on bulk material can trace hydration...
