Abstract
The reaction of Ru5(CO)15(μ5-C), 1, with Ph3GeH at 150 °C has yielded two new germanium-rich pentaruthenium cluster complexes: Ru5(CO)11(μ-CO)(μ-GePh2) 3(μ5-C), 2; Ru5(CO)11(μ-GePh2)4 (μ5-C), 3. Both compounds contain square pyramidal Ru5 clusters with GePh2 groups bridging three and four of the edges of the Ru5 square base, respectively. When treated with 1 equiv of Ph3GeH at 150 °C compound 2 is converted to 3. Reaction of 3 with H2 at 150 °C yielded Ru5(CO)10(μ-GePh2)4 (μ5-C)(μ-H)2, 4, containing two hydride ligands and one less CO ligand. Reaction of 4 with hydrogen at 150 °C yielded the compound Ru5(CO)10(μ-GePh2)2 (μ3-GePh2)2(μ3-H) (μ4-CH), 5, by loss of benzene and conversion of two of the bridging GePh2 groups into triply bridging GePh groups. Compound 5 contains one triply bridging hydride ligand and a quadruply bridging methylidyne ligand formed by addition of one hydrogen atom to the carbido carbon atom.
