Which one is the example of tridentate ligand?
diethylenetriamine
Well-known tridentate ligands include diethylenetriamine with three nitrogen donor atoms, and the iminodiacetate anion which consists of one deprotonated amine nitrogen and a pair of carboxylate groups.
What are some examples of ligands?
Examples of common ligands are the neutral molecules water (H2O), ammonia (NH3), and carbon monoxide (CO) and the anions cyanide (CN-), chloride (Cl-), and hydroxide (OH-). Occasionally, ligands can be cations (e.g., NO+, N2H5+) and electron-pair acceptors.
How do you identify a tridentate ligand?
Tridentate Ligands and Polydentate Ligands Tridentate ligands have three lone pairs of electrons to the central metal atom or ion. Molecules with four donor atoms are called tetradentate, five donor atoms are called pentadentate and six donor atoms are called hexadentate.
Is Dien a tridentate ligand?
Dien (diethylenetriamine) is a tridentate ligand.
Which is the example of hexadentate ligand?
Ethylene diamine tetra acetate ion [EDTA] is an example of hexadentate ligand.
What are polydentate ligands explain one example?
Polydentate ligands range in the number of atoms used to bond to a central metal atom or ion. EDTA, a hexadentate ligand, is an example of a polydentate ligand that has six donor atoms with electron pairs that can be used to bond to a central metal atom or ion.
What are ligands What are their types give one example?
Ligands : The neutral molecules or negatively charged anions (or rarely positive ions) which are bonded by coordinate bonds to the central metal atom or metal ion in a coordination compound are called ligands or donor groups. For example in [Cu(CN)4]2-, four CN- ions are ligands coordinated to central metal ion Cu2+.
What are monodentate ligands write one example?
Monodentate ligands are Lewis bases that donate a single pair (“mono”) of electrons to a metal atom. Monodentate ligands can be either ions or neutral molecules. The one example are halide ions such as Cr,F−,I− and cyano, etc.

Which of the following is tridentate neutral ligand?
Ptn is tridentate neutral Ligand.
What is ligand give an example of Tridentate and a hexadentate ligand?
Tridentate ligands have three atoms capable of binding to a central metal atom or ion. Molecules with four donor atoms are called tetradentate ligands; five donor atoms, pentadentate; and six donor atoms hexadentate. The image shown below of EDTA binding to a central metal atom is an example of a chelate.
What are some examples of tridentate ligands?
[1] Well known tridentate ligands include diethylenetriamine with three nitrogen donor atoms, and the iminodiacetic anion made from iminodiacetic acid with one nitrogen and a pair of carboxylate groups. Molecules with four donor atoms are called tetradentate ligands ; five donor atoms , pentadentate ; and six donor atoms hexadentate .
What is a tetradentate ligand?
Ligands with three lone pairs of electrons to donate to the central metal atom or ion are called tridentate ligands, ligands with four donor atoms are called tetradentate, ligands with five donor atoms are called pentadentate, ligands with six donor atoms are called hexadentate and so on.
Which of the following is an example of hexadentate ligand?
Ans: EDTA is an example of a hexadentate ligand that binds four times at oxygen atom and twice at nitrogens. It is generally used in the form of salt or dry form and is a great chelating agent which forms multiple bonds in coordination compounds. Ans: Dioxygen complexes are an example of coordination compounds that contain O 2 as a ligand.
What is a ligand?
A ligand is an ion or molecule capable of donating a pair of electrons to the central metal atom and in doing so form a coordination compound. Ligands play a very important role in Coordination Chemistry. Ligands usually act as electron-pair donors ( Lewis Bases) and the central atom acts as electron-pair acceptors ( Lewis acids ).
