Compound 2a was subjected to a crystallographic study which reveals severe intramolecular overcrowding; the palladium atom is slipped by 0.56 Å away from the C-bound phenyl groups, the co-ordination of the cod ligand to the metal is... GO Kyd,LJ Yellowlees,AJ Welch - 《Journal of the Ch...
A new azido derivative of tridentate Schiff base copper(II) complex has been synthesized and characterized. X-ray single crystal structure analysis reveals that the complex [Cu2L2(N3)2(NO3)2] (1), containing 1-(N-pyridylimino)-3-aminopropane (L) as co-ligand, is a dimer in which coppe...
Atom RSS Feed X-ray tomography, or X-ray computed tomography, is a method for generating 3-dimensional imaged volumes from 2-dimensional X-ray image slices. X-ray imaging is based on the differential absorption or scattering of an X-ray source to reveal the internal attributes of a structure...
Atom RSS Feed X-ray crystallography is a technique that uses X-ray diffraction patterns to determine high-resolution, three-dimensional structures of molecules such as proteins, small organic molecules, and materials. The substance of interest must be in crystalline form, which typically requires test...
A single-crystal X-ray study of (Me3Si)3CLi·tmen (tmen =N,N,N′,N′-tetramethylethylenediamine) shows that it crystallises with the ionic structure [Li(tmen)2][Li{C(SiMe3)3}2] but that the anions pack with different orientations from th... AG Avent,C Eaborn,PB Hitchcock,.....
X-ray structure of simian immunodeficiency virus integrase containing the core and C-terminal domain (residues 50-293) - an initial glance of the viral DNA... The crystal structure of simian immunodeficiency virus (SIV) integrase that contains in a single polypeptide the core and the C-terminal...
AsFig. 1shows,X-ray crystallographyis arguably the most widely used biophysical technique in medicinalchemistry. In single-crystal X-Ray a monochromatic beam of X-Rays, which can be considered as electromagnetic waves, is directed at the crystal and the diffraction pattern that is generated is me...
The syntheses and single crystal X-ray structure determinations are reported for [Li(thf)4][SnCl5(thf)] (1) and {[Li(Et2O)2]2-(μ-Cl2)2-SnIVCl2} (2). Compound 1 is ionic with a tetrahedral coordinated lithium cation and distorted octahedral tin (IV) atom in the anion, while comp...
In both compounds the azapolyether ligands coordinate a central barium atom in a meridional fashion, with the hfac ligands on opposite sides of the neutral ligand plane. The basic coordination geometries of complexes 1 and 2 are thus analogous to those in most of the barium β-diketonate ...
The class of oxo-donor atom ligands is the most prevalent in actinide coordination chemistry, owing to their predominant use in separation chemistry of the f-elements. Aqua species. A number of investigations of trivalent actinide ions in aqueous media have been directed at identifying the coordinat...
