S. Haak et al., Conversion of ethylene into ethylidyne on a mixed-metal cluster: synthesisand structure of IrRu4(CO)(15)(mu(4)-CH3), INORG CH C, 2(2), 1999, pp. 60-61
The thermal reaction of the tetranuclear cluster HIrRu3(CO)(13) with ethyle
ne in hexane (90 degrees C, 2 bar) affords, in addition to H3IrRu3(CO)(12),
the pentanuclear cluster HIrRu4(CO)(15)(mu(4)-C-CH3) (1) in which the ethy
lidyne ligand is coordinated through a carbon atom to the four ruthenium at
oms in the IrRu4 core. In this reaction, the CH2=CH2 molecule has been tran
sformed into a C-CH3 moiety coordinated as a mu(4)-ligand to the cluster. (
