Denticity

[Joelle Tran 1K]

How does the denticity of a ligand affect the naming of a coordination compound? Could someone give an example of a compound that has a bidentate versus monodentate ligand?

If you have a polydentate ligand then the prefixes, bis, tris, tetrakis, pentakis are used in front of it same as if you have a ligand with prefixes of bi, tri, tetra, etc in front of it. Hope this helps !

Like a previous comment said, if it is polydentate you would use the the prefixes bis, tris- depending on the number of the ligand. You can refer to 9c.1 in the textbook for examples of polydentate ligands and examples of compounds that have them. Off the top of my head, ethylenediamine is a bidentate ligand, but I can't think of a compound that contains it. In a compound you would prefix it as bisethylenediamine/trisethylenediamine/etc depending on the number.

Denticity affects the prefixes when naming. If something is polydentate you would use the prefixes -bis, -tris, -tetrakis, as oppose to -bi, -tri, etc. Something that is polydentate is (dien) and something that is monodentate is (NH3) for example.
