The electronically unsaturated complex [Ru-3(CO)(8)(mu(3)-CMe)(mu-H)(2)(mu(3)-H)](2) (1), viewed as a dimer of the 46-electron fragment Ru-3(CO)(8)(mu(3)-CMe)(mu-H)(3), is held together by delocalized bonding involving two triply bridging hydride ligands. Compound 1 exhibits a dynamic activity in solution that equilibrates two of the three types of hydride ligands. Compound 1 reacts with 1,1-bis(diphenylphosphino)methane to form the macrocyclic complex [Ru-3(CO)(7)(mu(3)-CMe)(mu-H)(3)](2)(mu-dppm)(2) (3).
