Molecular structure of a new tetranuclear μ2:μ3-bis-vinylidene cluster, Cp2(CO)4RePd(μ-CCHPh)RePd(μ3-CCHPh)(η2-dppe)

The novel tetranuclear di-vinylidene complex Cp2(CO)4RePd(μ2-CCHPh)RePd(μ3-CCHPh)(dppe) was isolated and characterized by X-ray diffraction. This cluster consists of two RePd fragments linked to each other through the bonding of the palladium atom in the [Cp(CO)2RePd(μ-CCHPh)] fragment to the carbonyl and vinylidene ligands in the Cp(CO)2RePd(μ-CCHPh)(dppe) fragment.

A new di-vinylidene cluster was isolated and characterized by X-ray diffraction. The metal core of the cluster consists of four alternating rhenium and palladium atoms, Re–Pd–Re–Pd. The cluster contains two vinylidene ligands, which coordinate to the metal core in two different manners.Figure optionsDownload as PowerPoint slide
