Defining a Ligand

Postby Hector Acosta Discussion 1H » Sat Nov 18, 2017 12:57 am

I have no prior knowledge to what a ligand is so can someone please give me a very basic definition of it.

The ligand is the molecule that donates a pair of electrons in a coordination compound. In other words, it is a lewis base.

A ligand is a molecule with a lone pair of electrons. It forms coordinate (dative) bonds with transition metal cations. If it only has one lone pair, it is called "monodentate", if it has more than one lone pair and can form more than one coordinate bond, it is called "polydentate".

Can someone further explain the relationship between ligands and coordination spheres and how they relate to the coordination number??
