用过量的[Rh（Cod）2][SbF 6]（cod =环辛-1，5-二烯）处理五钌盐[N（PPh 3）2]2[Ru 5C（CO）14]，得到单阴离子[Ru 5 RhC（CO）14（cod）]-，其分离为[N（PPh 3）2]+盐1。一价阴离子与HBF_4·Et_2O反应，生成配体[Ru_5RhH（C）（CO）_（14）（cod）]_2。化合物1分别与金盐[Au（PPh 3）]Cl和[Au（PEt 3）]Cl反应，得到簇合物[Ru 5 RhC（CO）14（cod）{Au（PPh 3）}]3和[Ru 5 RhC（CO）14（cod）{Au（PEt 3）}]4。化合物3的晶体属于三斜晶系空间群P（no.2），a= 15.993（3），B= 9.728（2），c= 13.900（3）A，α= 90.29（2），β= 99.97（2），γ= 88.36（2）°。金属核几何结构由中心Ru 5 Rh八面体组成，其中一个Ru 3面被µ3-Au（PPh 3）片段覆盖[Ru-Ru 2.787（1）-3.093（1）; Ru-Rh 2.892（1）-2.952（1）; Ru-Au 2.735（1）-3.082（1）A]。报道了化合物3和4与降冰片二烯、PPh_3和P（OMe）_3的反应。
Treatment of the pentaruthenium salt [N(PPh3)2]2[Ru5C(CO)14] with an excess of [Rh(Cod)2][SbF6](cod = cycloocta-1,5-diene) yielded the monoanion [Ru5RhC(CO)14(cod)]– which has been isolated as its [N(PPh3)2]+ salt 1. Reaction of the monoanion with HBF4·Et2O gave the hydrido derivative [Ru5RhH(C)(CO)14(cod)]2. Compound 1 reacted with the gold salts [Au(PPh3)]Cl and [Au(PEt3)]Cl, respectively, to yield the cluster compounds [Ru5RhC(CO)14(cod){Au(PPh3)}]3 and [Ru5RhC(CO)14(cod){Au(PEt3)}]4. Compound 3 crystallises in the triclinic space group P(no. 2) with a= 15.993(3), b= 9.728(2), c= 13.900(3)A, α= 90.29(2), β= 99.97(2), γ= 88.36(2)°. The metal core geometry consists of a central Ru5Rh octahedron with one Ru3 face capped by a µ3-Au(PPh3) fragment [Ru–Ru 2.787(1)–3.093(1); Ru–Rh 2.892(1)–2.952(1); Ru–Au 2.735(1)–3.082(1)A]. The reactions of 3 and 4 with norbornadiene, PPh3 and P(OMe)3 are reported.
