Abstract

One of the three products of the reaction, earlier reported, between [Cp*Rh(CO)₂] (Cp* = ?⁵-C₅Me₅) and [Ru₃(CO)₁₂] in toluene at 70°C in the presence of gaseous H₂ has now been fully characterised as [Cp*₂Rh₂Ru₂(µ₃-CO)₂(CO)₆]. A single crystal X-ray diffraction study {space group Ccca, a 16.019(3), b 19.168(3), c 20.743(3) Å; 2697 independent reflections with I>3s(I); final R = 0.037, R₂ = 0.050} has revealed a tetrahedral metal core with triply-bridging CO ligands on the two Rh₂Ru faces. This structure is consistent with IR and ¹³C{¹H} and ¹H NMR spectra, although the ion of highest mass in the FAB-mass spectrum is [M - 28]⁺, formed by loss of CO from the parent cluster. The cluster is readily cleaved at ambient temperatures by reaction with CO or H₂. © 1988.
