N2 - The reaction of [IrH5(PPh3)2] with [{M(cod)Cl}2] (M = Rh or Ir, cod = cyclo-octa-1,5-diene) gives the dinuclear complexes [(η4-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 adopts a square-planar co-ordination 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 [Ir(1)-Cl(1) 2.352(8), Ir(2)-Cl(1) 2.534(8) Å], and this asymmetry is discussed in terms of the relative trans effect of the ligands present.
