Polyazine‐bridged Ru II Rh III Ru II complexes with two halide ligands, Cl − or Br − , bound to the catalytically active Rh center are efficient single‐component photocatalysts for H 2 O reduction to H 2 fuel, with the coordination environment on Rh impacting photocatalysis. Herein reported is a new, halide‐free Ru II Rh III Ru II photocatalyst with OH − ligands bound to Rh, further enhancing the photocatalytic reactivity of the structural motif. H 2 production experiments using the photocatalyst bearing OH − ligands at Rh relative to the analogues bearing halides at Rh in solvents of varying polarity (DMF, CH 3 CN, and H 2 O) suggest that ion pairing with halides deactivates photocatalyst function, representing an exciting phenomenon to exploit in the development of catalysts for solar H 2 production schemes.
