Coordination compounds

Coordination compounds are a special class of compounds in which the central metal atom is surrounded by ions or molecules beyond their valency.

There are also referred to as coordination complexes or complexes.

The interesting thing of coordination compounds is that these are formed from apparently saturated molecules capable of independent existence.
