The carbonyl complex [OsII(NH3)5(CO)]2+ undergoes a photolysis in aqueous solution which yields [OsVI(NH3)4N]3+ (Φ = 10−3 at λirr = 255 nm) and methanol. This photoreduction of CO to CH3OH represents a novel type of photoreactivity of metal carbonyl complexes and could be utilized for an artificial photosynthesis.
