Single-crystal XRDNickel coordination compoundMixed ligandsThe title compound is monomeric with a Ni(II) hexacoordinated center. The coordination sphere is formed with four nitrogens from two neocuproine molecules and two oxygens from a sulfate ion that acts as a bidentate ligand. A water ...
Its crystal structure was determined by single-crystal XRD investigation and belongs to the original structure type (refined composition Ho2Cr2C2.9, R = 2.7%). Unit cell parameters were also refined from Guinier powder pattern using α-quartz as an internal standard. It was detected in the as...
"single crystal X-ray diffraction analysis"的analysis可以不要,关键的问题是单晶xrd是表征手段吧,应该说"characterized by single crystal X-ray diffraction"的 -N-phenylbenzamide was synthesized and characterized by 1H NMR, 13C NMR, MS, IR and X-ray diffraction methods. The struc...
Single-crystal XRD: Single-crystal XRD allows for absolute structure determination. With single-crystal XRD data, the exact atomic positions can be observed, and thus bond lengths and angles can be determined. This technique provides the structure within a single crystal, which does not necessarily...

Single crystal X-ray diffraction (XRD) is a powerful non-destructive method which allows unambiguously identify crystalline phases, determine a crystal structure (unit cell parameters, a space group, atomic coordinates and atomic occupancies) and, if required, a phase composition. This thesis deals...

Accurate XRD, often in combination with ND, has long been used to study electron density features in crystalline compounds. The method is particularly successful for light-atom systems in which the valence-to-core electron ratio is high. The same method is clearly applicable to the study of (...
molecular nitrogen surrounding the laser absorbers was also heated, albeit likely to a lower temperature, producing multiple tiny ( < 500 nm) high-quality single-crystals on which Raman spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction (SCXRD) data were collected....
