Polydentate

Postby 005388369 » Thu Dec 05, 2019 10:32 am

How do we know which ligands are polydentate by looking at the coordination compound formula? For example, in HN(CH2CH2NH2)2?

From looking at the coordination compound formula you can tell which ligands are polydentate by the number of highly electronegative atoms they contain. In this example there are three nitrogens with lone pairs that can bond to the central metal atom so the molecule would be tridentate.
