Systematic experimental charge density analysis of anion receptor complexes.
The first systematic electronic resolution study of a series of urea-based anion receptor complexes is presented. The hydrogen bonding in these multi-component systems was fully characterised using Bader's Quantum Theory of Atoms In Molecules (QTAIM) with the strength of the various N-H···anion hydrogen bonds quantified and the individual contributions of different intermolecular forces to the ...
متن کاملExperimental charge density from electron microscopic maps.
The charge density (CD) distribution of an atom is the difference per unit volume between the positive charge of its nucleus and the distribution of the negative charges carried by the electrons that are associated with it. The CDs of the atoms in macromolecules are responsible for their electrostatic potential (ESP) distributions, which can now be visualized using cryo-electron microscopy at h...
متن کاملExperimental charge density of N-phenylurea
Urea and its derivatives have been the subject of extensive experimental and theoretical studies, using many techniques, mainly because of interesting physical and chemical properties [1-4]. Here we report a preliminary results of charge density study of N-phenylurea using synchrotron diffraction data collected at beamline F1 at HASYLAB/DESY. Although known from literature [1], the structure wa...
متن کاملCharge density analysis for crystal engineering
This review reports on the application of charge density analysis in the field of crystal engineering, which is one of the most growing and productive areas of the entire field of crystallography. While methods to calculate or measure electron density are not discussed in detail, the derived quantities and tools, useful for crystal engineering analyses, are presented and their applications in t...
متن کاملCharge Density Analysis in Magnesium Hydride
Magnesium is considered one of the most promising materials for reversible hydrogen storage, because it has high storage capacity. However, the high thermodynamic stability of magnesium hydride is unfavorable for dehydrogenation processes. Understanding the bonding nature of Mg and H is essential for improving its dehydrogenation performance. Therefore, the charge density distribution in MgH2 w...
