A Rh (III) complex having a functionalized bpy-OH ligand that is potentially linkable to electrode surfaces was synthesized and fully characterized. The hydrido complex, which could be generated either electrochemically by cathodic reduction of the [η5-Cp∗ Rh (bpy- OH) Cl] Cl complex at− 771mV (versus Ag/AgCl) or chemically with formate, transformed NAD+ efficiently into NADH with a TOF= 710 at 60° C.
