... The donor atoms in tetrahedral coordination do not overlap well with the metal d-orbitals, so that Δtet is much smaller than Δoct in octahedral complexes with the same ligands, e.g. [Co(NH3)4]2+ versus [Co(NH3)6]2+. Calculation suggests Δtet ≈ 4/9 Δoct in that situation. Note the lack of a g in the ...

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.
