Pentadentate

Postby George Cazares 1E » Sun Nov 29, 2020 12:07 pm

Can there be ligand that bind to 5 sites and be pentadentate or more than 6 sites? In Dr. Lavelle's notes, he has monodentate, bidentate, tridentate, and hexadentate, but are there others?

There exists tetradentates, pentadentates, and octadentates. I'm guessing there is a cap to how many atoms a ligand can bind to, but I'm not sure on that exact number.

Dr. Lavelle did mention that pentadentates do exist but they're not as common. Hexadentates are common since compelxes often have octahedral geometry. I don't think it goes past hexadentate but I'm not sure. I am sure 6 sites is more than enough for Chem 14A which is why he only mentioned the common ones :)

Hope this helps!
