Full title: Some new rhodium(I)-iridium(III) complexes with bridging hydride and chloride ligands. Synthesis of compounds [L2Rh(μ-H)(μ-Cl)IrH2L′2] (L = PEt3 or L2 = diphos; L′ = PEt3, P-i-Pr3) and the X-ray crystal structure of [(PEt3)2Rh(μ-H)(μ-Cl)IrH2(PEt 3)2]. The reaction of [IrH5(PEt3)2] with complexes containing the unit RhClL2 (L = PEt3 or L2 = diphos, Ph2PCH2CH2PPh2) give compounds [L2Rh(μ-H)(μ-Cl)IrH2(PEt3)2]. The molecular structure of 8a (L = PEt3) was determined by X-ray diffraction: monoclinic, space group P21/c, Z = 4, a = 11.507 (2) A?, b = 15.974 (4) A?, c = 19.198 (4) A?, β= 103.19 (4)°. The structure was solved by Patterson and Fourier methods using 4946 observed reflections (I ≥ 3σ(I)) and refined to a conventional R = 0.059. The coordination around rhodium is distorted square planar, and that around iridium is distorted octahedral. The Rh-Ir distance is 2.898 (1)A?, and the bridging chlorine atom is asymmetrically bonded to the two metals. The structural features of this complex are compared with those of a series of related mono- and binuclear complexes. The formation of the dichloro-bridged complex [(diphos)Rh(μ-Cl)2IrH2(P-i-Pr3)2] is also reported.
