What is the example of hexadentate ligand?
A hexadentate ligand in coordination chemistry is a ligand that combines with a central metal atom with six bonds. One example of a hexadentate ligand that can form complexes with soft metal ions is TPEN. A commercially important hexadentate ligand is EDTA.
What are bidentate ligands give example?
Bidentate ligands have two donor atoms which allow them to bind to a central metal atom or ion at two points. Common examples of bidentate ligands are ethylenediamine (en), and the oxalate ion (ox).
What are pentadentate ligands?
[¦pen·tə¦den‚tāt ′lī·gənd] (inorganic chemistry) A chelating agent having five groups capable of attachment to a metal ion. Also known as quinquidentate ligand.
Is EDTA is Hexadentate?
In polynuclear lanthanide complexes EDTA molecule acts as a heptadentate ligand which is unprecedented.
How many donor atoms are present in a hexadentate ligand?
It has 2 N and 4 O donor atoms. Thus, EDTA is a hexadentate ligand.
Why is EDTA called as hexadentate ligand?
As we can see from the structure that it has six donor atoms , that is , two nitrogen and four oxygen atoms ( of the carboxylic acid groups ) capable of bonding to the metal atom . Hence it is a hexadentate ligand .
What are bidentate ligands give one example class 12?
Bidentate ligands: The ligands which bind to central metal through two donor atoms are called bidentate ligands. 1. Ethylenediammine binds to the central metal atom through two nitrogen atoms.
What is meant by Denticity?
In coordination chemistry, denticity (from Latin dentis ‘tooth’) refers to the number of donor groups in a given ligand that bind to the central metal atom in a coordination complex.
What is a chelate ligand give one example?
Chelating ligands are also sometimes called a multidentate ligand. The compounds that are formed by these compounds are called chelates. A popular example of a chelating ligand is ethylenediamine (NH2 CH2 CH2 NH2). It can form a bond with a metal ion using the two nitrogens present.
What is hexadentate ligand class 12?
Flexi-dentate ligands are poly-dentate ligands that do not use all their donor atoms to coordinate to the metal ion. In some complexes, they use a different number of donor atoms. EDTA – Ethylene diamine tetraacetic acid is an example of Flexi-dentate ligands.
Why is EDTA called a hexadentate ligand?
