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*2Rh2Ru23-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.
