yields. Homo‐ and heterobimetallic complexes of the type [(n‐Bu)4N][M(CO)5(μ‐SR)M′(CO)5] (M, M′ = W, Mo, Cr), in which both the exocyclic S‐atom and the endocyclic N‐atom are involved in coordination to two metal centers, have been prepared by the reaction of [(n‐Bu)4N][M(CO)5SR] with M′(CO)5·THF at ambient temperatures. The methods of preparation and characterization of these complexes are described.
