One of the major challenges in homogeneous catalysis is the use of first row transition metals as catalysts. The reactivity of these metals is fundamentally different from their heavier and rarer noble metal counterparts that are currently often employed in catalysis. First row transition metals tend to form high spin complexes, for example, and they are typically more prone to 1e - reactivity than noble metals. In nature, enzymes often employ multiple earth abundant metals in one active site to facilitate catalysis using the cooperative action of the metal centers. This sparked the growing interest in using complexes with multiple first row metal atoms in close proximity, to control their reactivity by using this metal-metal cooperativity (MMC). The area of MMC in coordination chemistry is still relatively underdeveloped, hence it is important to gain a better fundamental understanding of this phenomenon and the effect that it has on the reactivity of metal complexes.
