With the two nitrogen atoms, which can donate their lone pairs of electrons, ethylenediamine is widely used as a chelating ligand for coordination chemistry to form bonds to a transition-metal ion such as nickel (II).3The bonds form between the metal ion and the nitrogen atoms of ethylenediami...
[29,35]. Expectedly, the algal NOEC in standard tests is considerably lower being in the range of 10 mg/l [29] which can be explained by the already discussed deprivation of trace metals essential for algal growth. On the other hand, stimulation effects of EDTA also on algal growth have...
Chemical Synthesis: N-METHYLETHYLENEDIAMINE is commonly used as a building block in organic synthesis. It can be used as a ligand in coordination chemistry and as a catalyst in various reactions. Its mechanism of action in chemical synthesis involves its ability to form complexes with metal ions,...
A small amount of complexometrically neutral magnesium salt of EDTA is therefore added to the buffer, a step which automatically introduces sufficient magnesium and at the same time obviates a blank correction. The sharpness of the endpoint increases with increasing pH. The pH, however, cannot be...
groups and two nitrogen atoms acting as ligand sites. Thus the compound is a hexadentate ligand. Ligands include ions such as Cl-, NO2-and CN- or neutral molecules like NH3and H2O, which possess a lone pair of electrons that can be shared with a metal cation in coordinate covalent bonds...
It is widely employed both as a ligand for metal ions and as a catalyst in organic polymerisation. 3.2 Description Colorless to slightly yellow liquidChEBI: An ethylenediamine derivative in which each nitrogen carries two methyl substituents. It is widely employed both as a ligand for metal ions ...
Of particular interest are the noticeable effects of some new platinum compound with edda-type ligand on cell lines that are known to have a high level of cisplatin-resistance. Exanimate complexes appear to have a different mode of mechanism of action compared with cisplatin which includes ...
The sodalite-type structure of the framework consists of BTTri(3-)-linked [Cu(4)Cl](7+) square clusters in which each Cu(II) center has a terminal DMF ligand directed toward the interior of a large pore. The framework exhibits a high thermal stability of up to 270 degrees C, as ...
a new derivative of type (b), N,N,N',N'-tetrakis((4-butoxypyridin-2- yl)methyl)ethylenediamine (TBPEN), was synthesized, and Cd, which is one of the soft metals, extraction test was carried out. All reagents used in the extraction experiments were of reagent grade and were used ...
Thus the compound is a hexadentate ligand. Ligands include ions such as Cl-, NO2-and CN- or neutral molecules like NH3 and H2O, which possess a lone pair of electrons that can be shared with a metal cation in coordinate covalent bonds.The water solubility of EDTA is very low and, ...
