Nickel atoms were inserted into nine-atom deltahedral Zintl ions of E(9)(4-) (E = Ge, Sn) via reactions with Ni(cod)(2) (cod = cyclooctadiene), and Ni@Sn(9) was structurally characterized. Both the empty and the Ni-centered clusters react with TlCp (Cp = cyclopentadienyl anion) and add a thallium vertex to form the deltahedral ten-atom closo-species E(9)Tl and Ni@E(9)Tl, respectively. The structures of Ge(9)Tl and Ni@Sn(9)Tl showed that, as expected, the geometry of the ten-atom clusters is that of a bicapped square antiprism where the Tl-atom occupies one of the two capping vertices. This illustrates that centering a nine-atom cluster with a nickel atom does not change its reactivity toward TlCp. All compounds were characterized by electrospray mass spectrometry.
镍原子通过与 Ni(cod)2（cod = 环辛二烯）的反应插入到 E(9)(4-)（E = Ge、Sn）的九个原子的 deltahedral Zintl 离子中，并且对 [Ni@Sn(9)]3-进行了结构表征。空簇和 Ni 中心簇都与 TlCp（Cp = 环戊二烯基阴离子）反应，并添加一个铊顶点，分别形成 deltahedral 十个原子的 closo-物种 E(9)Tl和 Ni@E(9)Tl。Ge(9)Tl和 Ni@Sn(9)Tl的结构表明，正如预期的那样，十个原子簇的几何形状是双帽四方反棱柱体，其中 Tl 原子占据两个盖帽顶点之一。这说明用镍原子中心九个原子簇不会改变其对 TlCp 的反应性。所有化合物均通过电喷雾质谱法进行了表征。
