Abstract

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.
