The coordination numbers of Li + , Na + , K + , Cl − , Br − , I − have been determined at 25°. In dilute solutions they are close to the mean coordination number of the water molecule in water. The following expression is proposed as a measure of the hydration of ions;...
2.3.3 The coordination number The coordination number (CN, sometimes called hydration number when the solvent is water) is a useful metric for characterizing the solvation structure around a solute molecule and can also provide insights into the solubilization behavior of drug molecules in solution. ...

The high coordination number of Eu3+-Lnot only benefits to sufficient sensitization of the Eu3+ion based on the antenna effect, but also prevents luminescent quenching caused by the infiltration of water molecule, thus endowing the lanthanide coordination polymer with characteristic emission color and...

Scientific Reports volume 11, Article number: 21974 (2021) Cite this article 2551 Accesses Metrics details Abstract Joint operation of the Longyangxia and Liujiaxia reservoirs (Long-Liu operation) is of great significance for water and sediment regulation in the Yellow River. The water–sediment–...
At the same time, coordination of water transport and growth seemingly should differ between plant functional types. We evaluated the relationships between water transport, growth and species stature in six species of co-occurring trees and shrubs. Within species, a strong proportionality between plant...
It provides a service for viewing and downloading a harmonised Digital Terrain Model (DTM) for the European sea regions that is generated by the EMODnet Bathymetry partnership on the basis of an increasing number of bathymetric data sets. These are managed as survey data sets and composite DTMs...
and sp3hybridization ofvalence electronsof the carbon atom leads to a limited number of possible geometries in organic compounds, namely, linear, trigonal-planar, and tetrahedral. One asymmetrical sp3hybridized carbon atom generates one pair ofenantiomers, while an asymmetrical sp3d2or d2sp3hybridized...
Single-crystal X-ray diffraction finds that nanoconfined water has an ordered structure that is characteristic in ices, but infrared spectroscopy reveals a significant number of broken hydrogen bonds that is characteristic in liquids. We find that their structural properties are quite similar to those ...
