Carbonyl-iridium half-sandwich compounds, Cp*Ir(CO)(EPh)2 (E=S, Se), were prepared by the photo-induced reaction of Cp*Ir(CO)2 with the diphenyl dichalcogenides, E2Ph2, and used as neutral chelating ligands in carbonylmetal complexes such as Cp*Ir(CO)(μ-EPh)2[Cr(CO)4], Cp*Ir(CO)(μ-EPh)2[Mo(CO)4] and Cp*Ir(CO)(μ-EPh)2[Fe(CO)3], respectively. A trimethylphosphane-iridium analogue, Cp*Ir(PMe3)(μ-SeMe)2[Cr(CO)4], was also obtained. The new heterodimetallic complexes were characterized by IR and NMR spectroscopy, and the molecular geometry of Cp*Ir(CO)(μ-SePh)2[Mo(CO)4] has been determined by a single crystal X-ray structure analysis. According to the long Ir...Mo distance (395.3(1) A), direct metal-metal interactions appear to be absent.
