Desilylation of 2 with KF/THF/MeOH afforded the hexatriynylcarbene complex [(CO)5WC(NMe2)CCCCCCH] (4). Deprotonation and coupling with ClSnnBu3 gave the C-stannylated carbene complex [(CO)5WC(NMe2)CCCCCCSnnBu3] (5). Reaction of 5 with nBuLi and [ClRu(CO)2Cp] afforded the heterobimetallic heptatriynylidene-bridged complex [(CO)5WC(NMe2)CCCCCCRu(CO)2Cp] (6). The trinuclear complex [(CO)5WC(NMe2)CCCCCC–Hg–CCCCCC(Me2N)CW(CO)5] (7) was obtained by reaction of 4 with nBuLi and HgCl2. All new compounds are stable at room temperature. Spectroscopic data suggest weak interaction of the metal centers in 6 and 7.</dcterms:abstract> <dcterms:title>Synthesis of triynylcarbene complexes and of bi- and trinuclear complexes with heptatriynylidene C7-bridges</dcterms:title> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/23042"/> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> </rdf:Description> </rdf:RDF>
