Xz. Zhou et al., THE FIRST SILA-BRIDGED DICYCLOPENTADIENYL DIRUTHENIUM COMPLEX - SYNTHESIS AND X-RAY STRUCTURE OF (ME2SI)[(ETA(5)-C5H4)RU(CO)](2)(MU-CO)(2), Inorganica Chimica Acta, 262(1), 1997, pp. 109-112
Thermal treatment of a solution of Ru-3(CO)(12) and C5H5Me2SiC5H5 in h
eptane gives (Me2Si) [(eta(5)-C5H4)Ru(CO)](2)(mu-CO)(2) (1) in good yi
eld. An investigation on the infrared spectra of 1 in KBr disc and CH2
Cl2 solution reveals the coexistence of two isomers la (bridging form)
and 1b (non-bridging form), with the former dominant. The molecular s
tructure of 1a has been determined by X-ray diffraction.
