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)93- GetBu)2, 1, Ru2(CO)6(μ-Ge tBuH)3, 2, Ru4(CO) 104-Ge2 t Bu 2)(μ-GetBuH)2, 3, Ru4 (CO) 84-Ge2 t Bu2)(μ- GetBuH)23-GetBu)(H), 4, Ru 5 (CO)123- GetBu) 24-GetBu)(H), 5, Ru6(CO) 123-GetBu)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.
