“…The triphenylgermanium ligand is coordinated to Ru(1), occupying an equatorial site as expected, and the Ru(1)-Ge 1bond distance of 2.5054(3) Å is comparable to the terminally coordinated GeMe3 ligands in C8H6[(CO)2Ru(GeMe3)]2 (mean 2.487 Å) [25]. The gross structural features of 1 are similar to those displayed in the related trimetallic clusters [Ru3(CO)9(SiPh3)(µ-dppm)(µ-H)] [26] and [Os3(CO)9(GePh3)(µ-dppm)(µ-H)] [7] reported by us. The solution spectroscopic data for 1 indicate that the solid-state structure persists in solution.…”

“…Fortunately, several closely related silyl analogs have been reported, and we were able to reconcile the recorded data for 4 against the silyl congeners. The IR spectrum recorded for 4 closely matches the IR data for a series of Ru3(CO)7(µ-CO)(SiR3)(µ-H){µ3-PhPCH2P(Ph)C6H4} clusters [26]. The spectrum exhibits seven carbonyl absorptions, of which six appear from 2079 to 1932 cm -1 and one a weak absorption appears at 1865 cm -1 .…”

The activation of Ph3GeH at the dppm-bridged cluster Ru3(CO)10(µ-dppm) [dppm = bis(diphenylphosphino)methane] has been investigated. Ru3(CO)10(µ-dppm) reacts with Ph3GeH at room temperature in the presence of Me3NO to give the new cluster products Ru3(CO)9(GePh3)(µ-dppm)(µ-H) (1) and Ru3(CO)8(GePh3)2(µ-dppm)(µ-H)2 (2) via successive oxidation-addition of two Ge-H bonds. Refluxing 1 in THF furnishes the diruthenium complex Ru2(CO)6(µ-GePh2)(µ-dppm) (3) as the major product (44%), in addition to Ru3(CO)7(µ-CO)(GePh3){µ3-PhPCH2P(Ph)C6H4}(µ-H) (4) and the known cluster Ru3(CO)9(µ-H)(µ3-Ph2PCH2PPh) (5) in 7 and 8% yields, respectively. Heating samples of cluster 2 also afforded 3 as the major product together with a small amount of Ru3(CO)6(GePh3)(µ-OH)(µ-dppm)(µ-H)2 (6). DFT calculations establish the stability of the different possible isomers for clusters 1, 2, and 6, in addition to providing insight into the mechanism for hydride fluxionality in 2. All new compounds have been characterized by 2 analytical and spectroscopic methods, and the molecular structures of 1, 3, and 6 have been established by single crystal X-ray diffraction analyses.
