Formic acid is decomposed to H2 and CO2 in the presence of RuCl3 and triphenylphosphines in an emulsion. In situ formed ruthenium carbonyls, such as [Ru(HCO2)2(CO) 2(PPh3)2] (1), [Ru(CO)3(PPh 3)2] (2), and [Ru2(HCO2) 2(CO)4(PPh3)2] (3), and a large cluster, involving a Ru12 core, were identified and structurally characterized from the reaction mixtures. The catalytic activity of the mono and binuclear complexes was also investigated and it was found that [Ru 2(HCO2)2(CO)4(PPh3) 2] (3) shows high stability even at elevated temperatures and pressures and its activity is 1 order of magnitude lower than those measured for the mononuclear complexes. It was also attempted to use [Ru(HCO 2)2(CO)2(PPh3)2] (1) as a catalyst for the hydrogenation of CO2 to formic acid under neutral conditions. Although the reduction of CO2 did not take place, the conversion of [Ru(HCO2)2(CO)2(PPh 3)2] (1) to an unexpected carbonate, [Ru(CO 3)(CO)2(PPh3)2]·H 2O was observed.

The decomposition of a HCO2H/Et3N azeotrope to a mixture of hydrogen and carbon dioxide may be catalyzed by a number of Ru(III) and Ru(II) complexes with high efficiency at ca. 120 °C. Evidence that suggests that the precatalyst may
