The title complex (Me2SiSiMe2)(η5-l-indenyl)Fe(CO)]2(μ-CO)2 (1) was prepared by the reaction of 1,2-bis(1-indenyl)tetramethyl-disilane and Fe(CO)5 in refluxing heptane. Its thermalrearrangement product [Me2Si(η5-1-indenyl)Fe(CO)2]2 (2) was also obtained from the reaction. 1 in refluxing xylene can be readily converted into 2. The crystal structures of the cis isomer 1c and the trans isomer 2t were

Thermal treatment of C9H7SiMe2C9H7 and C9H7Me2SiOSiMe2C9H7 with Ru-3(CO)(12) in refluxing xylene gave the corresponding diruthenium complexes (E)[(eta(5)-C9H6)Ru(CO)](2)(mu-CO)(2) [E = Me2Si (1), Me2SiOSiMe2 (2)]. A desilylation product [(eta(5)-C9H7)Ru(CO)](2)-(mu-CO)(2) (3) was also obtained in the latter case. Similar treatment of C9H7Me2SiSiMe2C9H7 with Ru-3(CO)(12) gave a novel indenyl nonanuclear ruthenium cluster Ru-9(mu(6)-C)(CO)(14)(mu(3)-eta(5):eta(2):eta(2)-C9H7)(2) (5) with carbon-centered tricapped trigonal prism geometry, in addition to the diruthenium complex (Me2SiSiMe2)[(eta(5)-C9H6)Ru(CO)](2)(mu-CO)(2) (4) and the desilylation product 3. Complex 4 can undergo a thermal rearrangement to form the product [(Me2Si)(eta(5)-C9H6)Ru(CO)(2)](2) (6). The molecular structures of 1, 2, 4, 5, and 6 were determined by X-ray diffraction.
