Abstract: The new mixed-metal clusters [CO2Ir2(CO)10(cod)] (4) and [CoIr3(CO)10(cod)] (5) (cod = 1,5-cyclooctadiene) have been obtained from [CO2(CO)8](2) and [IrCl(Cod)2] (3). Alternatively, [CO2Ir2(CO)12] (1) reacts with cod to yield 4, which in the presence of CO reforms 1. Under the same conditions, however, 5 is inert. The solid state structures of 4 and 5 have been established by X-ray analyses, and the disorder shown by the two species is discussed. Compound 4 is monoclinic, space group P21/c, a 8.891(2), b 10.746(3), c 22.648(8) Å, β 95.16(3)°, Z = 4, R = 0.048, R′= 0.050, for 2393 [I ≫ 2σ(I)] of 2596 absorption corrected reflections; compound 5 is also monoclinic, space group P21/m, a 8.5994(9), b 12.047(3), c 10.799(3) Å, β 98.30(1)°, Z = 2, R = 0.037, R′= 0.040, for 2071 [I ≫ 2σ(I)] of 2711 absorption corrected reflections. © 1993.
