The complex [Ru2(μ-CO)(CO)4(μ-dppm)2] is more active than mononuclear ruthenium complexes as a catalyst for decomposition of formic acid to CO2 and H2; under conditions of highest activity, a coordinatively unsaturated diruthenium dihydride [Ru2H(μ-H)(μ-CO)(CO)2(μdppm)2] is present and can be isolated from solution.

The chemistry of the coordinatively unsaturated hydridodiruthenium complex cation [Ru2(μ-H)(μ-CO)(CO)3-(μ-dppm) 2]+, 1, is described. Complex 1 adds CO to give [Ru 2(μ-H)(μ-CO)(CO)4(μ-dppm)2] +, reacts with hydrogen to give [Ru2(μ-H) 2(CO)4(μ-dppm)2] and H+ and, in the presence of Et3N, is an efficient catalyst for decomposition of formic acid to CO2 and H2. Complex 1 reacts easily with acetylene to give [Ru2(μ-CH=CH2)(CO) 4(μ-dppm)2]+, with PhCCH to give the coordinatively unsaturated alkenyl complex [Ru2{C(Ph)=CH 2}(μ-CO)2(CO)2(μ-dppm)2] + which then rearranges to the isomeric, coordinatively saturated complex [Ru2(E-μ-CH=CHPh)(CO)4(μ-dppm) 2]+, and reacts reversibly with PhCCPh to give [Ru 2{Z-C(Ph)=CHPh}(μ-CO)2(CO)2(μ-dppm) 2]+.

The complex [Ru2(u-CO)(CO)4(u-dppm)2] in acetone solution is an efficient catalyst for the reversible reaction between formic acid and hydrogen/carbon dioxide. Complexes identified during the catalytic reactions include the hydrido and formato complexes [Ru2(u-H)(u-CO)(CO)4(u-dppm)2]+, [Ru2(u-HCO2)(CO)4(u-dppm)2]+, [Ru2(n-H)2(CO)4(u-dppm)2], [Ru2H(HCO2)(CO)4(u-dppm)2] and the coordinatively unsaturated [Ru2H(u-H)-(u-CO)(CO)2(u-dppm)2].
