Abstract The oxygen‐evolving complex (OEC) located in photosystem II (PSII) of green plants is one the best‐known examples a manganese‐containing enzyme nature, but it also used range other biological processes. OEC models incorporate two multi‐dentate nitrogen‐containing ligands coordinated to bis‐μ‐oxo Mn(III,IV) core. Open‐chain were initial scaffold for biomimetic studies, their macrocyclic counterparts have proven be particularly appropriate due enhanced stability. Dimer and monomer complexes with such shown useful wide applications, which will reviewed herein. purpose this review state some clarity different spectroscopic structural characteristics Mn formed tetraaza both solution solid‐state that allow reader successfully identified species involved when dealing similar Mn.
