Rb4Sn4与ZnPh2在液氨中[2.2.2]-隐晶体存在下反应生成Rb-6[(eta(2)-Sn-4)Zn(eta(3)-Sn-4)]中心点5NH(3)晶体，该晶体可以用x射线单晶衍射表征。这是高电荷四面体Sn-4（4-）阴离子溶液反应成功的第一个例子。同感[E4ZnE4]（6-）配合物（E =四元）以前只知道E=Ge和Si/Ge。
The reaction of Rb4Sn4 with ZnPh2 in liquid ammonia in the presence of [2.2.2]-cryptand yielded crystals of Rb-6[(eta(2)-Sn-4)Zn(eta(3)-Sn-4)]center dot 5NH(3), which could be characterized by single crystal X-ray diffraction. This is the first example of a successful solution reaction of the highly charged tetrahedral Sn-4(4-) anions. The homoleptic [E4ZnE4](6-) complex (E = tetrel element) was previously known only for E=Ge and Si/Ge.
