Structural and reactivity insights into high-valent Co(iii)–(μ-peroxo)–Co(iv) and its electromer Co(iii)–(μ-superoxo)–Co(iii)

The current study reveals an elegant equilibrium between previously unprecedented high-valent electromer complexes, Co( iii )-(μ-1,2-peroxo)-Co( iv ) and Co( iii )-(μ-1,2-superoxo)-Co( iii ), stabilized by the electron-donating TPA* ligand.
