What exactly is a ligand?

Postby janeane Kim4G » Wed Dec 05, 2018 4:02 pm

Exactly as the topic states, I have no idea what a ligand is and it’s significance/ what it’s used for. Does anyone have a simplified explanation for dummies?

A ligand is anything that binds to a transition metal like Cobalt, copper. etc. Examples of ligands are water, ammonium, and cyanide
The way this happens is by forming a coordination covalent bond, where the 2 lone pairs of a ligand are shared between the metal and the ligand. Hope this helps

A ligand is whatever ion or molecule is bonded to a metal atom through a coordinate bond. It's basically the electron pair donor. A coordinate bond is a covalent bond (which is when electrons are shared) in which the two electrons were provided by the same atom. Some common ligands are Cl-, Br-, F-, and I-. So when NH3 bonds to Ni (nickel), NH3 is the ligand because it's bonded to a metal atom and it provides the electron pair.
