| Abstract: | The reaction of Ir6(CO)16 with a mixture of CO, H2, and ethylene yields the Ir6(CO)15COEt]- anion, which has been shown by X-ray diffraction to contain an octahedral iridium cluster bearing a —bonded acyl group; the arrangement of the 11 terminal and 4 edge-bridging carbonyl groups is different from that found in both the analogous rhodium complex and the parent Ir6(CO)16 carbonyl. |
