coordination number=polydentate number?

Postby Mei Blundell_1J » Thu Jun 07, 2018 7:42 pm

Does the number of coordination bonds in a coordination compound always equal the number of bonds that a ligand makes with the central metal atom (polydentate number)?

Yes, I believe it does. My TA said coordination number is not equal to the number of ligands, but it's equal to the number of LIGAND ATTACHMENTS (or bonds) to the central atom.

it is related to how many bonds the molecules can make with the central atom

Thanks guys, I think that if there are multiple ligands on the metal, though, that the polydentate number of each ligand does not necessarily equal the coordination number of the whole complex. I definitely have to think about this more.

Does coordination number include double bonds?

I think double bonds are considered as one total ligand attachment.
