... Accordingly, it should be expected that [Zn(NH3)4]2 would be tetrahedral, and that is correct. In 1893, Alfred Werner proposed a theory to explain the existence of complexes such as CoCl36NH3, CoCl34NH3, PtCl22NH3, and Fe(CN)33KCN. He began by assuming that a metal ion has two kinds of valence. ...

Coordination complex
In chemistry, a coordination complex or metal complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals, are coordination complexes.
