The presence of the ligands near the metal ion changes the energies of the metal d orbitals relative to their energies in the free ion. Both the color and the magnetic properties of a complex can be attributed to this crystal field splitting. The magnitude of the splitting depends on the nature of the ligands bonded to the metal.

Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid (electron pair acceptor). Ligands have at least one donor atom with an electron pair used to form covalent bonds with the central atom. Ligands can be anions, cations, or neutral molecules.

These complexes contain a central atom or ion, often a transition metal, and a cluster of ions or neutral molecules surrounding it.

For example, the complex of Ni(II) with three ethylenediamine ligands should be chemically similar to the Ni(II) complex with six ammonia ligands. In fact, the equilibrium constant for the formation of the ethylenediamine complex is almost 10 orders of magnitude

Ligands can, however, be bidentate (two-toothed, from the Greek di, meaning “two”), tridentate (three-toothed, from the Greek tri, meaning “three”), or, in general, polydentate (many-toothed, from the Greek poly, meaning “many”), indicating that they are attached to the metal at two, th
