The photoreduction of aqueous protons to hydrogen under anaerobic conditions induced by osmocene dissolved in 1,2-dichloroethane and the subsequent water splitting by the osmocenium metal-metal dimer formed during H(2) production were studied by electrochemical methods, UV-visible spectrometry, gas chromatography, and nuclear magnetic resonance spectroscopy. Density functional theory computations were used to validate the reaction pathways.Proceedings of the National Academy of Sciences of the United States of AmericaBiphasic water splitting by osmocene.PMC3406862121577200021257096Corminboeuf COlaya AJGirault HHTodorova TKMendez MHu XPatir IHVrubel HGe PfalseBiphasic water splitting by osmocene.The photochemical reactivity of osmocene in a biphasic water-organic solvent system has been investigated to probe its water splitting properties.
