Carbido carbonyl ruthenium clusters

Carbide, iron complex, 26 246 Carbido carbonyl ruthenium clusters. 

The formation of carbido-carbonyl cluster compounds with ruthenium and osmium appears to be common in pyrolysis reactions the basic reaction may be viewed as the transformation of the coordinated carbon monoxide to carbide and carbon dioxide. Small variations in...

The first hexanuclear cluster obtained was for ruthenium, as the carbonyl-carbido RuflCfCO). This was prepared by heating Ru3(CO) 2 in... 

Interest in the high nuclearity carbonyl clusters of ruthenium has centered around the hexanuclear carbido-cluster Ru6C(CO)17 and its derivatives, Ru5C(CO)15 and, more recently, [Ru C CO) ]2-.1 The chemistry of both Ru6C(CO)17 and Ru5C(CO)15 has been investigated in some detail. Their syntheses are described below. 

The chemistry of metal cluster carbonyls containing carbido ligands dates back to the discovery and characterization of the first example, Fc5C(CO)i5, in 1962. For the metal ruthenium, many examples of clusters with different nuclearity are... 

Syntheses of medium- and high-nuclearity ruthenium and osmium clusters continue to be largely by thermolyses of lower nuclearity precursors, but surface-mediated methods have also been employed the use of inorganic oxides or zeolites in the preparation of metal carbonyl clusters, including pentaosmium and hexaruthenium carbido clusters, and the decaosmium complexes [H50sio(CO)24] and [Osio(/t6-C)(CO)24], has been reviewed.
