“…However, the structure of 50 is similar to those found for related clusters with acyclic diaminocarbene 45 or Fischer carbene 46 ligands. Indeed, the conversion of [Ru 3 (m 3 -S) 2 (CO) 9 ], the ''parent'' cluster of 48, to [Ru 4 (m 4 -S) 2 (m-CO) 3 (CO) 8 ], the ''parent'' cluster of 50, upon reaction with triruthenium [Ru 3 (CO) 12 ] has been achieved, 47 thereby providing a plausible reaction pathway for the formation of 50.

In the last decade, chemists have dedicated many efforts to investigate the coordination chemistry of N-heterocyclic carbenes (NHCs). Although most of that research activity has been devoted to mononuclear complexes, transition-metal carbonyl clusters have not escaped from these investigations. This critical review, which is focussed on the reactivity of NHCs (or their precursors) with transition-metal carbonyl clusters (mostly are of ruthenium and osmium) and on the transformations underwent by the NHC-containing species initially formed in those reactions, shows that the polynuclear character of these metallic compounds or, more precisely, the close proximity of one or more metal atoms to that which is or can be attached to the NHC ligand, is responsible for reactivity patterns that have no parallel in the NHC chemistry of mononuclear complexes (74 references).

294ChemInform Abstract The triruthenium cluster (I) reacts with the Mo dimer (II) to give the three heterometal clusters (III)-(V). These are chromatographically isolated and characterized by IR and 1H NMR spectra as well as by X-ray structure analysis of (IV) (space group P21/c, Z=4) and (V) (P21/m, Z=2). Both the products (IV) and (V) contain π-bound µ4-CO ligands. The clusters (IV) and (V) can also be obtained by reaction of (III) with Ru(CO)5 at 80 rc C in 23 and 15% yield, respectively.
