摘要：
Addition of PhC=CR(R = H, Ph) to [Ru-5(mu(5)-C-2>(mu-SMe>(2)(mu-PPh(2))(2)-(CO)(11)] 1 results in the formation of [Ru-5(mu(5)-CCCPhCR)(mu-SMe)(2)(mu-PPh(2))(2)-(CO)(10)] (R = H 2, Ph 3), the mu(5)-CCCPhCR ligand being formed by coupling of the alkyne with the C-2 ligand of 1; in 2 the pentagonal Ru-5 cluster of 1 is retained while 3 an extra Ru-Ru bond is formed, yielding an envelope-type structure; corresponding differences in the attachment of the organic ligand to the Ru-5 cluster are found.
