Mimicking sMMOH chemistry: trapping the Sc 3+ -bound nonheme Fe III –O–O–Fe III adduct prior to its conversion into an Fe IV 2 (μ-O) 2 core

The data in this paper represent the first documented evidence for Lewis-acid adduct formation to a 1,2-peroxodiferric species derived from the reaction of a diiron(
