Interplay and Competition Between Two Different Types of Redox‐Active Ligands in Cobalt Complexes: How to Allocate the Electrons?

Abstract: The field of molecular transition metal complexes with redox‐active ligands is dominated by compounds with one or two units of the same redox‐active ligand; complexes in which different redox‐active ligands are bound to the same metal are uncommon. This work reports the first molecular coordination compounds in which redox‐active bisguanidine or urea azine (biguanidine) ligands as well as oxolene ligands are bound to the same cobalt atom. The combination of two different redox‐active ligands leads to mono‐ as well as unprecedented dinuclear cobalt complexes, being multiple (four or six) center redox systems with intriguing electronic structures, all exhibiting radical ligands. By changing the redox potential of the ligands through derivatisation, the electronic structure of the complexes could be altered in a rational way.
