Synthesis and Structure of a Novel Cluster with Trigonal-bipyramidal Ge2Ru3 Core

When t-BuC5H4Me2GeGeMe2C5E4Bu-t and Ru3 (CO)12 were refluxed in nonane, a novel germanium-ruthenium duster with a trigonal-bipyramidal Ge2Ru3 core {(μ3-Ge) [Ru(CO)2 (η5-C5H4Bu-t)]}2Ru3 (CO)9 (1) and a dinuclear ruthenium complex [(Me2Ge)(η5-C5H3Bu-t)Ru2(CO)6] (2) were obtained. The structures of 1 and 2 were fully characterized by 1H NMR, 13C NMR, IR spectra and elemental analysis, and 1 has also been determined by X-ray diffraction analysis.
