Abstract

In heptane solvent, Ru₃(CO)₁₂ reacts with tertiary butyl germane at reflux, to afford six new bimetallic ruthenium-germanium carbonyl cluster complexes Ru₃(CO)₉(μ₃- Ge^tBu)₂, 1, Ru₂(CO)₆(μ-Ge ^tBuH)₃, 2, Ru₄(CO) ₁₀(μ₄-Ge₂ ^t Bu ₂)(μ-GetBuH)₂, 3, Ru₄ (CO) ₈(μ₄-Ge₂ ^t Bu₂)(μ- Ge^tBuH)₂(μ₃-Ge^tBu)(H), 4, Ru ₅ (CO)₁₂(μ₃- Ge^tBu) ₂(μ₄-Ge^tBu)(H), 5, Ru₆(CO) ₁₂(μ₃-Ge^tBu)₄(H)₂, 6. Complex 2 was obtained as a result of cluster fragmentation while cluster condensation provided higher nuclearity ruthenium-germanium complexes 3-6 with varying Ru-Ge ratios. All six compounds were structurally characterized by a combination of IR, 1H NMR, mass spectrometry and single-crystal X-ray diffraction analyses.
