Complex dication [{Ru(L-N4Me2)}2{μ-tape-(SO3)2}]2+ ([4]2+) was exploited as a redox mediator between an anaerobic homogenous reaction solution of an enzyme system (sulfite/sulfite oxidase) and the electrode by participation of the low-energy π*-orbital of the disulfonato-substituted bridging ligand tape–(SO3)22−. Tape diruthenium complexes could be a new valuable group of artificial redox mediators. The redox potential of these complexes can be easily modified for the required purpose by different substituents at the bridging tape and the terminal macrocycle.
