Cation-cation interaction (CCIs) in novel layered and framework uranyl compounds

Dissecting the cation-cation interaction between two uranyl units.

We present a state-of-the-art computational study of the uranyl(vi) and uranyl(v) cation-cation interactions (dications) in aqueous solution. Reliable electronic structures of two interacting uranyl(vi) and uranyl(v) subunits as well as those of the uranyl(vi) and uranyl(v) clusters are presented for the first time. Our theoretical study elucidates the impact of cation-cation interactions on ch...

GROWTH RESPONSE AND CATION - INTERACTION IN HIPPOPHAE RHAMNOIDES L

The interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of Hippophae rhamnoides L. The results demonstrated that an addition of sodium with calcium, (set a, Na 2.5 + Ca 5 mM) showed prominent increase in fresh weight of roots and shoots. The dry weight (average) of roots decreased an...

The cation-π interaction.

The chemistry community now recognizes the cation-π interaction as a major force for molecular recognition, joining the hydrophobic effect, the hydrogen bond, and the ion pair in determining macromolecular structure and drug-receptor interactions. This Account provides the author's perspective on the intellectual origins and fundamental nature of the cation-π interaction. Early studies on cyclo...
