Redox-Mediated Self-Organization of Metallosupramolecular Architectures Composed of D-Penicillaminato CuI8CuII6 Clusters: Drastic Structural Change by Subtle pH Changes

pH‐dependent architecture: Cluster‐based metallosupramolecular compounds, which are composed of [CuI6CuII8(D‐pen)12Cl]5− (D‐H2pen=D‐penicillamine) cluster anions linked by Co2+ and/or K+ cations through D‐pen carboxylate groups, were spontaneously synthesized by simple treatment of K[CoIII(D‐pen)2]...

Description
Summary:pH‐dependent architecture: Cluster‐based metallosupramolecular compounds, which are composed of [CuI6CuII8(D‐pen)12Cl]5− (D‐H2pen=D‐penicillamine) cluster anions linked by Co2+ and/or K+ cations through D‐pen carboxylate groups, were spontaneously synthesized by simple treatment of K[CoIII(D‐pen)2] with CuICl in potassium acetate buffer solutions, accompanied by the redox between CoIII and CuI mediated by thiolate.
