Heptacarbonylbis([mu]3-[eta]2-diphenylacetylene)([eta]5-pentamethylcyclopentadienyl)triiridiumtungsten

A. C. Willis, G. T. Dalton and M. G. Humphrey

Abstract: The title compound, [WIr3([eta]-C10H15)([mu]3-[eta]2-C14H10)2(CO)7], is a mixed-metal cluster with a tetrahedral metal core geometry. One diphenylacetylene ligand is [mu]3-[eta]2-coordinated to the triiridium face, while the other is [mu]3-[eta]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.
