Abstract

The compound Ru4(CO)11(µ4-Te)2 (1) has been prepared by refluxing a benzene solution containing Fe3(CO)9(µ3-Te)2 and Ru3(CO)12. The compounds Ru3(CO)6(PPh3)3(µ3-Te)2 (2) and Ru4(CO)10(PPh3) (µ4-Te)2 (3) were obtained from the room temperature reaction of 1 with PPh3. Similarly, Ru4(CO)9 (µ - Ph2PCH2PPh2) (µ4 –Te)2 (4) was obtained from the reaction of 1 with Ph2PCH2PPh2 at room temperature. The structure of 1-4 were established by single-crystal X-ray diffraction analysis.
