Item Reversible dioxygen uptake at [Cu4] clusters(Royal Society of Chemistry, 2024) Osei, Manasseh Kusi; Mirzaei, Saber; Mirzaei, M. Saeed; Valles, Agustin; Sánchez, Raúl HernándezDioxygen binding solely through non-covalent interactions is rare. In living systems, dioxygen transport takes place via iron or copper-containing biological cofactors. Specifically, a reversible covalent interaction is established when O2 binds to the mono or polynuclear metal center. However, O2 stabilization in the absence of covalent bond formation is challenging and rarely observed. Here, we demonstrate a unique example of reversible non-covalent binding of dioxygen within the cavity of a well-defined synthetic all-Cu(I) tetracopper cluster.
