摘要：

Heating a mixture of W2Ir2(CO)(10)(eta -C5H4Me)(2) and 1,2-(E)-bis{4'-(oct-1"-ynyl)phenyl}ethene in refluxing CH2Cl2 affords a complex mixture from which W3Ir3(mu (4)-eta (2)-CO)(mu -CO)(CO)(10)(eta -C5H4Me)(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 mu (4)-eta (2)-CO ligand which has the longest carbonyl CO bond thus far.
