The dark side of the Mn : A manganese(III) complex bearing a 13‐membered macrocyclic ligand ( 1 , see picture) binds a peroxo ligand in a side‐on η 2 fashion. The reactivity of 1 is influenced by the introduction of anionic ligands trans to the peroxo group. Electronic and structural changes upon trans ‐ligand binding explain the increased nucleophilicity of the resulting complexes 1 ‐X.
