Reaction of the tris-hypersilyl nonagermanide Zintl cluster salt, K[Ge (Hyp) ] (Hyp=Si(SiMe ) ) with [Rh(η ,η -L)Cl] (L=1,5-cyclooctadiene, COD; norbornadiene, NBD) afforded eleven- and twelve-vertex homo-multimetallic clusters by cluster core expansion. Using a stepwise procedure, starting from the Zintl cluster [Rh(COD){Ge (Hyp) }] and [Ir(COD)Cl] , this methodology was expanded for the synthesis of eleven-vertex hetero-multimetallic clusters. A mechanism for the formation of these first examples of closo eleven-vertex Zintl clusters is proposed, informed by density functional theory calculations.
三超甲硅烷基九锗化物锌特耳簇盐K[Ge(Hyp)₉]（Hyp = Si(SiMe₃)₃）与[Rh(η⁵,η¹- L)Cl]（L = 1,5 - 环辛二烯，COD；降冰片二烯，NBD）反应，通过簇核扩展得到了十一个和十二个顶点的同多金属簇。采用逐步程序，从锌特耳簇[Rh(COD){Ge₉(Hyp)₉}]和[Ir(COD)Cl]开始，这种方法被扩展用于合成十一个顶点的异多金属簇。基于密度泛函理论计算，提出了这些闭式十一个顶点锌特耳簇首例形成的机制。
