Number of Ligands

Postby Nora 1F » Sun Nov 19, 2017 11:32 pm

What do you look at to determine the number of ligands in a given complex?

The number of ligands are determined by how many ions or molecules are attached to the central metal atom in a coordination complex.

For example, in Ni(CO)4, the Ni is the central atom and the CO molecules are the ligands. So in this coordination complex, there are four ligands.

Count the functional groups (ions or molecules) attached to the central atom. This is the number of ligands you have
