Studies of the synthesis, structure, and reactivity of a tetranuclear mixed-metal imido cluster, (η5-C5H5)WRu3(CO)9(µ-NPh)(CCPh)

Abstract

The title complex (η⁵-C₅H₅)WRu₃(CO)₉(µ-NPh)(CCPh), containing a bridging imido ligand and a µ₄-η²-acetylide ligand, has been prepared by means of the condensation between (η⁵-C₅H₅)W(CO)₃CCPh and Ru₃(CO)₁₀(µ₃-NPh), and its reactions with dihydrogen and disubstituted alkyne ligands are presented; the products have been fully characterized by spectroscopic methods and X-ray diffraction studies for two complexes.
