Abstract
The new Rh-Co mixed-metal dimer [Rh2Co2(CO)8(μ-CO)2(μ4,η2-HC≡CCH2O-)]2C6H4 4 and trimer [Rh2Co2(CO)8 (μ-CO)2(μ4,η2-HC≡CCH2O-)]3B 5 have been synthesised from reactions between Rh2Co2(CO)12 1 and the appropriate diyne and triyne ligands. The crystal structure of cluster 4 has been determined.
