Synthesis of a Mixed-Metal Cluster Complex of Rhenium and Nickel [Re3NiS4Cl6(PEt3)4]

Condensation of [Ni(cod)2] with a trinuclear rhenium chloro sulfido cluster complex prepared from [Re3S7Cl6]Cl and triethylphosphine forms a mixed metal cluster complex [Re3NiS4Cl6(PEt3)4]. The cluster complex has 17 metal cluster electrons and is paramagnetic. The four metal atoms form a cubane structure with face-capping sulfur atoms.
