Coordination Complexes and Ligands - Purdue University

The number of ligands bound to the transition metal ion is called the coordination number. Although coordination complexes are particularly important in the chemistry of the transition metals, some main group elements also form complexes. Aluminum, tin, and lead, for example, form complexes such as the AlF 6 3-, SnCl 4 2-and PbI 4 2-ions.

AmmLeach A New Paradigm in Copper Cobalt Processing

In the ammoniacal system, aerial oxidation will convert all of the cobalt to the trivalent form and this forms the basis of the separation of copper and cobalt. Although copper can also be present in a monovalent form, the ammine complex is almost impossible to form except under anaerobic conditions.
