cas 1703-58-8, 1,2,3,4-Butanetetracarboxylic acid

The reaction of with 2> (M = Rh or Ir, cod = cyclo-octa-1,5-diene) gives the dinuclear complexes 4-C8H12)M(μ-H)(μ-Cl)IrH2(PPh3)2>.The di-iridium compound has been subjected to an X-ray analysis which establishes that the iridium(I) atom adpots a square-planar coordination geometry while the iridium (III) atom is in a pseudo-octahedral environment if the direct Ir-Ir interaction is ignored.The two Ir atoms are bridged by a hydride and a chloride ligand.The Ir-Cl bridge is highly asymmetric , and this asymmetry is discussed in terms of the relative transeffect of the ligands present.
