A diiron dithiolate complex 1 containing 1,8‐naphthalic anhydride bridge was prepared, which possessed the lowest reduction potential for the synthetic diiron complexes modeled on the active site of [FeFe] hydrogenase reported so far. For the first time, oxidative quenching of the excited Ru(bpy) 3 2+ * through electron transfer to a bio‐inspired [2Fe2S] complex was corroborated. Hydrogen evolution, driven by visible light, was successfully observed for a three‐component system, consisting of Ru(bpy) 3 2+ , complex 1 , and EDTA as electron donor in aqueous/organic media. These results provide a basis and also opportunity to develop a photo water splitting system employing Fe‐based catalysts without sacrificial electron donors.
