Abstract

The reaction of [Os₃(CO)₁₂] with indene at 150°C under reflux affords the known compounds [H₂Os₃(CO)₉(C₉H₆)] (2) and [Os₄(CO)₁₂(C₉H₆)] (3). When the reaction temperature is increased to 170°C, the yield of 2 is greatly reduced, and a new tetraosmium cluster [HOs₄(CO)₉(C₉H₆)(C₉H₇)] (1) is isolated. An X-ray diffraction study of 1 has shown that one face of the Os₄ tetrahedron is capped by an indyne ligand coordinated in a μ₃-η²-- bonding mode, while the indenyl ligand (C₉H₇) is coordinated to a single Os atom in a η⁵ bonding mode through the five-membered ring.
