Mix and match: We report studies of hydrogen evolution catalyzed by [Cp*Rh] complexes bearing substituted bipyridine ligands. Involvement of multiple modes of metal–ligand cooperativity is found to give rise to effective catalysis, including formation of η⁴-Cp*H complexes en route to H₂ production. Synthetic and electrochemical studies support the assignment of a new mechanism of catalysis involving bpycentered reduction.
