The reaction of Ir(CO)2(p-toluidine)Cl with trans-bis(1,2-diphenylphosphino)ethylene in the presence of CO and Zn yielded Ir3(CO)7(μ-(cis-PPhCH=CHPPh2)). The complex formed orange-red multifaceted crystals; the structure was determined at -35°C and found to be characterized by the monoclinic space group P21/c with unit cell constants a = 12.574 (5) A?, b = 10.917 (3) A?, c = 21.606 (5) A?, β = 104.84 (3)° and Z = 4. Full-matrix least-squares refinement converged to R = 0.038 and Rw = 0.041. The average Ir-Ir bond distance in the triangular cluster is 2.771 (1) A?. The cis-PPhCH=CHPPh2 fragment acts as a tridentate (η1-P1,μ-P2,η2C=C) ligand.
