AbstractThe reactions of the activated tetraosmium carbonyl cluster [Os4(µ-H)4(CO)10(NCMe)2] 1 with some pyridyl-containing ligands, namely, 2,2′-bipyrimidine (bpm), 2,3-bis(2-pyridyl)pyrazine (dpp) and 2,3′-bis(2′-pyridyl)-5,6-dimethylquinoxaline (dpq), gave the new clusters: [Os4(µ-H)4(CO)10(bpm)] 2, [Os4(µ-H)4(CO)10(dpp)] 3 and [Os4(µ-H)4(CO)10(dpq)] 4, respectively. The molecular structures of clusters 2, 3 and 4 were established by X-ray diffraction analysis. Compound 3 underwent protonation to give the corresponding water soluble cationic cluster [Os4(µ-H)4(CO)10(dppH)]+ 5 which has been characterized by positive-mode electrospray mass spectrometric analysis of the aqueous phase. Incorporation of compound 3 as a building block in the heterometallic supramolecular system has also been established.
