摘　　要：利用金属交换法合成了四个新的含钌手性过渡金属簇合物［ＭＲｕＣｏ（ＣＯ）_８（μ_３－Ｓｅ）［η_５－Ｃ_５Ｈ_４Ｃ（Ｏ）Ｒ｝］（ １ Ｍ＝ Ｍｏ， Ｒ＝ ＯＥｔ； ２ Ｍ＝ Ｗ， Ｒ＝ ＯＥｔ； ３ Ｍ＝ Ｍｏ， Ｒ＝ ＣＨ_２ＣＨ_２ＣＯＯＭｅ； ４ Ｍ＝ Ｗ， Ｒ＝ ＣＨ_２ＣＨ_２ＣＯＯＭｅ），并用红外、核磁、元素分析测试结果进行表征，对簇合物１进行了单晶结构测定，晶体属单斜晶系，Ｐ２_１／ｎ空间群，晶胞参数ａ＝１０．１６８（２）Ａ，ｂ＝９．０１８（２）Ａ，ｃ＝２３．１２１（３）Ａ，β＝９２．５０（１）°，Ｚ＝４。Four new clusters [MRuCo(CO)_8(μ_3-Se) {η_5-C_5H_4C(O) R} ] (1 M = Mo, R = OEt; 2 M = W, R = OEt; 3 M = Mo, R = CH_2CH_2COOMe; 4 M = W, R = CH_2CH_2COOMe) were prepared by the reaction of [RuCo_2(CO)_ 9(μ_3-Se) ] and [M(CO)_3{η_5-C_5H_4C(O) R} ]^- (M = Mo or W, R = OEt or CH_2CH_2COOMe). They were characterized by elemental analysis, IR and ~1H NMR. and the structure of cluster 1 has been established by single crystal X-ray diffraction methods. Crystal Structure Data: P2_1/ n(No.14), monoclinic, a = 10. 168(2) A, b = 9. 018(2) A, c = 23. 121 (3) A, β = 92. 50(1)°, Z =4, V= 2118. 1 (6) A, Dc = 2. 183 g. cm^(-3), p = 37. 83 cm^(-1), 2θ_(max)= 51. 9°, and F(000) = 1328.
