Coordination Compounds
... In theory, any species with a lone pair of electrons can behave as a Lewis base and donate a pair of electrons to a central metal atom to form a coordination complex or compound. The term ligand is often used to describe any species that exhibits this kind of chemistry and literally hundreds of liga ...
