Tridentate ligands have three binding sites. This means, there are two atoms that can donate their lone electron pairs. Disodium ethylenediamine tetraacetate is a good sequesterant: 3. A single molecule of ethylenediamine can form two bonds to a metal ion. Ethylenediamine is a well-known bidentate chelating ligand for coordination compounds, with the two nitrogen atoms donating their lone pairs of electrons when ethylenediamine acts as a ligand. Chelating ligands are also sometimes called a multidentate ligand. Polydentate Ligands. Ethylene diamine is a example of a _____ ligand. The reaction proceeds by an initial Michael addition to the double bond to give the ring-opened intermediate ( 148 ) which cyclizes spontaneously to the 5-(2-hydroxyphenyl)-7-substituted-2,3-dihydro-1 H -1,4-diazepines ( 149 ) in high yield 〈82PJC83, 85S339〉 . The stability which a coordinate compound achieve due to the formation of chelate or ring by a polydendate ligand is called chelate effect.An example of a chelate ring occurs in the ethylenediamine-cadmium complex: Ligand, in chemistry, any atom or molecule attached to a central atom, usually a metallic element, in a coordination or complex compound.The atoms and molecules used as ligands are almost always those that are capable of functioning as the electron-pair donor in the electron-pair bond (a coordinate covalent bond) formed with the metal atom. The term ligand was proposed by the German chemist Alfred Stock in 1916. A ligand molecule with more than one donor atom is a called a polydentate ligand. A classic bidentate ligand is ethylenediamine, which is derived by the linking of two ammonia groups with an ethylene (−CH 2 CH 2 −) linker. Bidentate ligands are Lewis bases that donate two pairs ("bi") of electrons to a metal atom.. Bidentate ligands are often referred to as chelating ligands ("chelate" is derived from the Greek word for "claw") because they can "grab" a metal atom in two places.. A complex that contains a chelating ligand is called a chelate. ... etc. Bidentate ligands have two donor sites. 11. The bonds form between the metal ion and the nitrogen atoms of ethylenediamine.
