Abstract

Heating a mixture of W₂Ir₂(CO)₁₀(η-C₅H ₄Me)₂ and 1,2-(E)-bis{4′-(oct-1′′-ynyl)phenyl}ethene in refluxing CH₂Cl₂ affords a complex mixture from which W₃Ir₃(μ₄-η ²-CO)(μ-CO)(CO)₁₀(η-C₅H ₄Me)₃ can be separated in low yield. The crystallographically characterized title cluster is the first hexametallic Group 6-Group 9 mixed-metal cluster, possesses an unusual edge-bridged trigonal bipyramidal core geometry, and has a μ₄-η²-CO ligand which has the longest carbonyl CO bond thus far.
