摘　　要：The chiral cluster RuCoMo（CO）8 （μ3-Se）C5H4C （O）C6H4C （O）OCH3was synthesizgd by the thermal reaction of the precursor （μ3-Se）RuCo2（Co）9 with ’thefunctionally substituted cyclopentadienyl tricarbonyl metal complex anions [Mo（CO）3（η5-C5H4） C （O）C6H4C （O） OCH3]- in THF. It was characterized by C/H elementalanalysis, IR, 1H/13C-NMR and MS （FAB）, and its crystal structure has also beensolved by single-crystal X-ray diffraction. Crystal data: Mr=786. 23, triclinic, spacegroup P1, a =8. 200（2）, b= 19. 631 （7）, c=7.997（2） , a=92. 50（2）, β=108. 66 （2）, γ=88. 97（2）°, V= 1218. 5（6） , Z=2, Dc=2. 143g/cm3, F（000） =756. 00, μ= 33. 44cm-1, the final R =0. 054 and R.= 0. 077 for 2644 observationswith （I≥3.0σ（I） ）.
