摘要：

Reactions between Ru-5(mu(5)-C-2)(mu-SMe)(2)(mu-PPh2)(2)(CO)(11) (1) and butadiene afford Ru-5(mu(3)-C6H6)(mu(3)-SMe)(2)(mu-PPh2)(2)(CO)(10) (2), shown by a single-crystal X-ray structure determination to contain a mu(3)-eta(1):eta(1):eta(2) -cyclohex-1-en-4-yne ligand formed by cycloaddition of the diene to the C-2 fragment. The cluster has 80 c.v.e.; with only six Ru-Ru bonds a lengthening of three of them to between 3.003(2) and 3.144(2) Angstrom is found. The structure is compared to those of two other related 80 c.v.e. clusters. (C) 1999 Elsevier Science S.A. All rights reserved.
