3.1.1: Chelating Ligands

Denticity. Denticity refers to the number of atoms with which a ligand binds to a metal ion. A ligand could be monodentate, meaning it binds through a lone pair on a single atom.It could be bidentate, meaning it binds through lone pairs on two different atoms.It could even be tridentate, with three atoms bearing their own lone pairs, tetradentate, and so on.

Enantiomers in Octahedral Complexes with Bidentate Ligands

One example of a type of octahedral compounds that can form enantiomers is bidentate complexes. In bidentate complexes (from the Greek two teeth) or chelating complexes (from the Greek crab), a ligand binds very tightly to the metal because it holds onto the metal via more than one atom. Ethylenediamine is one example of a bidentate ligand.
