The reaction of Na[HRu3(CO)11] with an excess of tricyclohexylphosphine in methanol gives the neutral complex H2Ru3(CO)6(PCy3)3 which is the first 44 e- triruthenium cluster reported. This highly electron-deficient species reacts with carbon monoxide to give the saturated 48 e- cluster Ru3(CO)9(PCy3)3. The electronic structure of the novel 44 e- cluster was established by EHT and DFT molecular orbital calculations of isoelectronic model compounds. The analogous reaction of [N(PPh3)2][HOs3(CO)11] with PCy3 in methanol affords the 46 e- cluster H2Os3(CO)7(PCy3)3, the first trisubstituted derivative of H2Os3(CO)10. In all cases methanol acts as source of protons for the formation of the hydrido clusters.
