Switching of the redox centers of a tris-2-mercaptophenolato chromium(iii) metalloligand by a guest metal ion

Abstract

This work reports that the redox-active metalloligand (ML) fac-[CrIII(mp)3]3− (mp: 2-mercaptophenolato) coordinates with a Co(III) ion to afford the trianionic complex [CoIII{fac-CrIII(mp)3}2]3−. The free ML shows ligand-centered redox processes, whereas the guest-metal-bound trinuclear structure exhibited a guest-metal-centered Co(II)/Co(III) redox couple, demonstrating redox switching through guest-metal binding to the MLs.
