When they are different, the coordination numbers used can be different.

This would result in a coordination number of five.

On comparison to the classical coordination number, some major differences can be seen.

The coordination numbers of the two close packing lattices are both 12.

The two most common allotropes of carbon have different coordination numbers.

The coordination number of systems with disorder cannot be precisely defined.

In some cases the crystal structure changes so that the coordination number is not the same, and that can play an important role.

In smaller systems the coordination number for the surface is more significant and the magnetic moments have a stronger affect on the system.

In other complexes he found coordination numbers of 4 or 8.

The coordination number of Ba increases from 9 to 10.
