Polymorph identification and crystal structure determination by a combined crystal structure prediction and transmission electron microscopy approach.
Electron diffraction offers advantages over X-ray based methods for crystal structure determination because it can be applied to sub-micron sized crystallites, and picogram quantities of material. For molecular organic species, however, crystal structure determination with electron diffraction is hindered by rapid crystal deterioration in the electron beam, limiting the amount of diffraction da...
متن کاملCrystal engineering and IUCrJ
Crystal engineering is discussed, along with its three key concepts: crystal packing; the design of solids; and physical and chemical properties.
متن کاملBlind crystal structure prediction of a novel second polymorph of 1-hydroxy-7-azabenzotriazole.
The commercially available peptide coupling reagent 1-hydroxy-7-azabenzotriazole has been shown to crystallize in two polymorphic forms. The two polymorphs differ in their hydrogen-bonding motif, with form I having an R(2)(2)(10) dimer motif and form II having a C(5) chain motif. The previously unreported form II was used as an informal blind test of computational crystal structure prediction f...
متن کاملDatabase guided conformation selection in crystal structure prediction of alanine
Crystal structure prediction calculations have been performed for the a-amino acid alanine with the intention of developing reliable computational methods for flexible molecules and, specifically, to study the crystal packing of the more flexible amino acids. For the a-amino acids, the density functional theory geometry optimised conformations of the isolated molecules are considerably differen...
متن کاملCombined crystal structure prediction and high-pressure crystallization in rational pharmaceutical polymorph screening
Organic molecules, such as pharmaceuticals, agro-chemicals and pigments, frequently form several crystal polymorphs with different physicochemical properties. Finding polymorphs has long been a purely experimental game of trial-and-error. Here we utilize in silico polymorph screening in combination with rationally planned crystallization experiments to study the polymorphism of the pharmaceutic...
