Heterobimetallic phosphido-bridged complexes containing coordinatively unsaturated rhodium(I) and iridium(I) centers. Structural characterization of FeIr(μ-PPh2)(CO)5(PPh3)2

The series of new phosphido-bridged heterometallic binuclear complexes FeM(μ-PPh2)(CO)x(L)2 (M = Rh, L = PEt3, x = 4, 5; M = Ir, L = PPh3, x = 4-6) have been synthesized by the reaction of Li[Fe-(CO)4(PPh2)] with the appropriate irans-MCl(CO)L2 complex. The new complexes have been characterized spectroscopically, and FeIr(μ-PPh2)(CO)5(PPh3)2 has been characterized by a complete single-crystal X-ray diffraction study. It crystallizes in the space group P1 with a = 11.681 (3) A?, b = 20.869 (4) A?, c = 10.649 (9) A?, α = 96.74 (3)°, β = 108.86 (3)°, γ = 76.51 (2)°, V = 2386 (3) A?3, and Z = 2. Diffraction data (0° ≤ 2θ ≤ 50°) were collected with an Enraf-Nonius CAD4 automated diffractometer, using graphite-monochromatized Mo Kα radiation, and the structure was refined to R = 0.053 and Rw = 0.077 for 6257 independent reflections with I ≥ 3.0σ(I). The μ-PPh2 ligand bridges the Fe and Ir atoms, and each metal is ligated by a PPh3 ligand. The Fe is further ligated by three CO's and the Ir by two. The relatively long Fe-Ir bond length of 2.960 (1) A? suggests a weak donor-acceptor type interaction between the two metal centers. Each of the new compounds undergoes a series of reversible addition/elimination reactions with CO, and the Fe-Ir compounds react with H2 to give new H2 adducts.
