formula for coordination compounds

Postby Minh-Thy Vo 3D » Mon Nov 30, 2020 7:15 pm

When writing the formula for a coordination compound, is there a rule for the order of the ligands? Or can the ligands be in any order? Thank you!

Hi! When there is more than one ligand, you place them in alphabetical order. In today's lecture for example, [Co(NH3)5Cl], it would be penta ammine chloro cobalt (II) with ammine being before chloro.
Hope this helps :)

Also one thing I was struggling with is that if there are two or more ligands that need a prefix, put each in front of each ligand, rather than just 1 prefix.
