While the catalytic activity is low, the formation of an intermediate involving coordination of both hydride and bicarbonate to the ruthenium centre has been unambiguously established by <sup>1</sup>H, <sup>31</sup>P and <sup>13</sup>C NMR spectroscopy. Such an intermediate has previously been proposed on the basis of theoretical studies and experimental findings.In situ NMR characterisation of an intermediate in the catalytic hydrogenation of CO2 and HCO3– in aqueous solutiontext::journal::journal article::research article
