Abstract: A mixed tetranuclear cluster of ruthenium and cobalt, namely undecacarbonyl-tri--hydrido-(tricyclohexylphosphine)trirutheniumcobalt, [CoRu₃H₃(CO)₁₁(C₁₈H₃₃P)], has been synthesized by reaction between Co₂(CO)₈ and the electron-deficient cluster [Ru₃H₂(CO)₆(PCy₃)₃]. The compound was characterized, both spectroscopically and crystallographically. The molecular structure of [CoRu₃(-H)₃(-CO)(CO)₁₀(PCy₃)] shows a tetrahedral metal core. The tris(cyclohexyl)phosphine ligand is attached in an axial position to one of the Ru atoms of the basal face.
