... The Mn(acac)3 complex can be reversibly oxidized to Mn(acac)3+ (0.96 V vs SCE), or reduced to Mn(acac)3– (–0.06 V vs SCE) in acetonitrile solution (0.1 M tetraethylamonium perchlorate). It has been shown that many electron transfer reactions like those above are ligandcentered rather than metal-cent ...

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.
