3-
2-diphenylacetylene)(
5-pentamethylcyclopentadienyl)triiridiumtungstenAbstract: The title compound, [WIr3(
-C10H15)(
3-
2-C14H10)2(CO)7], is a mixed-metal cluster with a tetrahedral metal core geometry. One diphenylacetylene ligand is
3-
2-coordinated to the triiridium face, while the other is
3-
2-coordinated to a diiridiumtungsten face. The W atom is ligated by a pentamethylcyclopentadienyl ligand and a terminal carbonyl, and the Ir atoms are each ligated by two terminal carbonyls.
