coupling of complex 4 with [ClRu(CO),Cp] affords the heterobimetallic pentadiynylidenecomplex [(CO)5WC(NMe,)CCCCRu-(CO)2Cp] (5) The analogous Fe derivative [(CO),WC(NMe,)CCCCFe(CO)2Cp] (6) is obtained by sequential reaction of 3 with nBuLi and [IFe(CO)2Cp] Similarly, treatment of 3 first with nBuLi and then with half an equivalent of HgCl2 affords the novel C4HgC4-bridged biscarbene complex [(CO)3WC
