Abstract | The trinuclear osmium carbonyl cluster, [Os3(CO)10(MeCN)2], is allowed to react with 1 equiv. of [IrCp*Cl2]2 (Cp* = pentamethylcyclopentadiene) in refluxing dichloromethane to give two new osmium-iridium mixed-metal clusters, [Os3Ir2(Cp*)2(μ-OH) (μ-CO)2(CO)8Cl] (1) and [Os3IrCp*(μ-OH)(CO)10Cl] (2), in moderate yields. In the presence of a pyridyl ligand, [C5H3N(NH2)Br], however, the products isolated are different. Two osmium-iridium clusters with different coordination modes of the pyridyl ligand are afforded, [Os3IrCp*(μ-H)(μ-Cl)(η3 ,μ3-C5H2N(NH2)Br)(CO) 9] (3) and [Os3IrCp*(μ-Cl)2 (η2,μ3-C5H3N(NH)Br)(C O)7] (4). All of the new compounds are characterized by conventional spectroscopic methods, and their structures are determined by single-crystal X-ray diffraction analysis. © 2007 Elsevier B.V.
