Abstract

Coupled to coenzymes: Ruthenium (II) complexes having a pterin as a ligand, which is a redox-active heteroaromatic coenzyme, are synthesized and characterized to reveal that the complexes showed reversible proton-dependent redox behavior (see scheme). The pterin ligand undergoes proton-coupled electron transfer to form a ruthenium(II)-coordinated monohydropterin radical upon one-electron reduction.
