How to find the coordintion number of a compound?

Asked by Thomas Philip | 7th Jan, 2014, 08:50: AM

Expert Answer:

Coordination Number is the number of ligand- donor atoms (atoms, ions, or molecules) bonded directly to the central atom (metal).

So, to find the coordination number we can just look for the number of ligands bonded to the metal.


In [Ni(NH3)42+, Ni is linked to four NHmolecules. Hence, its coordination number is 4.

In [PtCl6]2− , Pt is linked to six Cl atoms. Hence, its coordination number is 6.
