Reaction of nitrobenzene with [M3(CO)12](M = Fe or Ru) in the presence of [Co2(CO)8]: isolation and structure of [Ru3(CO)7(NPh)(η6-C6H6)]
Abstract
The complexes [Ru3(CO)7(NPh)(C6H6)](1) and [FeCo2(CO)9(NPh)](2) are formed in the reactions between PhNO2 and [M3(CO)12](M = Ru or Fe) only when [Co2(CO)8] is present. The structure of (1) has been determined by X-ray diffraction; it contains triply bridging CO and PhN ligands and an η6-benzene ligand co-ordinated to only one metal atom.
