Perchlorate and Fluoride Complexes of Thallium(I) in Aqueous Solution.

Fluoride ion complexation by a cationic borane in aqueous solution.

The phosphonium borane [p-Mes(2)B(C(6)H(4))PMePh(2)](+) complexes fluoride in water containing 10% methanol with a binding constant of 1.0(+/-0.1) x 10(3) M(-1) to afford the zwitterion p-Mes(2)FB(C(6)H(4))PMePh(2).

A Review on Adsorption of Fluoride from Aqueous Solution

Fluoride is one of the anionic contaminants which is found in excess in surface or groundwater because of geochemical reactions or anthropogenic activities such as the disposal of industrial wastewaters. Among various methods used for defluoridation of water such as coagulation, precipitation, membrane processes, electrolytic treatment, ion-exchange, the adsorption process is widely used. It of...

Thermodynamic study of dioxovanadium (V) Complexes with p-sulphonato-calix [6] arene in aqueous solution

[Supramolecular chemistry of multinuclear zinc(II) complexes in aqueous solution].

We report novel supramolecular polyhedrons formed by three-dimensional self-assembly of multinuclear zinc(II)-12-membered tetraamine (= cyclen = 1,4,7,10-tetraazacyclododecane) complexes with potentially multidentate ligands such as cyanuric acid (CA) and trithiocyanuric acid (TCA) in aqueous solution. Two new supermolecular frameworks were isolated by self-assembly of a tris (Zn(2+)-cyclen) (Z...

The Structure of Zinc Chloride Complexes in Aqueous Solution

The structure of zinc chloride complexes with different ratios of chloride to zinc, formed in concentrated ZnCl2 aqueous solutions, were determined f rom large-angle X-ray scattering using concentrations of the chloride complexes estimated by complementary Raman spectroscopic measurements. The highest chloro complex, [ZnCl4]~, is tetrahedral with a Zn-Cl bond length of 2.294(4) Ä. The trichloro...
