| Abstract: | Three tetranuclear clusters Ru4H4(CO)11(PPh3)] (1), Ru4H2(CO)12(PPh3)] (2) and Ru3IrH(CO)12(PPh3)] (3) were formed in the reaction of Ir(CO)Cl(PPh3)2] and NaRu3H(CO)11] in tetrahydrofuran. Complexes 1–3 were characterized by IR and 1H and 31P NMR, and the structure of the clusters was confirmed by single crystal X-ray analysis. In 2 and 3 one of the carbonyls bridges between two ruthenium atoms; otherwise the compounds contain only terminal carbonyls. |
